Abstract
The proposed programme covers several very current challenges in polymer science. Polypeptide-based hybrid block copolymers prepared by ring-opening polymerization (ROP) offer a possibility to synergistically integrate the properties and functions of biomacromolecules and synthetic polymers in a single hybrid material, providing new and unique applications in nanotechnology and biotechnology. For preparation of such hybrid polymers the programme proposes a simple one-pot synthetic approach by sequential addition of monomers, which differ not only in reactivity but also propagate through different end-group types. Additionally, by combining ROP with emulsion-templating technique we aim to prepare the macroporous, synthetic polypeptide-based scaffolds that disclose a promising alternative to currently available 3D scaffolds for cell culturing, tissue engineering and regenerative medicine. Such biomimetic scaffolds will offer clear benefits by integration the morphological features of polyHIPE materials with the unique properties of synthetic polypeptides. ROP will also be used to prepare aliphatic polyesters distinguished by (bio)degradability, biocompatibility, and good mechanical properties. Aliphatic polyesters are already well-established materials in biomedicine, but they recently received increasing attention also in applications demanding sustainable materials. While the physical properties of polyesters can be tailored via the chemical composition and architecture, the conventional aliphatic polyesters lack functionality in the structure, which make their broader use largely limited. Our aim is therefore to introduce functional groups in polyester backbone via the ROP of functionalized lactone/lactide monomers prepared from biobased levulinic acid, which thus represents promising and innovative approach to engineering the material properties. The field of polymer nanocomposites covers innovative π-conjugated polyelectrolyte polyHIPE polymers with embedded nanostructured metal oxide semiconductors. Here, C-C coupling reactions in HIP emulsions will be applied to prepare macroporous nanocomposites applicable for the waste-water treatment by photo-oxidation. On the other hand, a major challenge in nanocomposites based on nanocellulose will be to functionalize the nanocellulose surface in a way to achieve effective formation of a cellulose percolation network throughout the polymeric matrix in order to significantly improve the mechanical properties of termoplastic polymers. The topic of environmental aspect of plastics deals with the studies of ecosystem pollution by plastic, and the new approaches to recycling of polymeric materials, where our focus will be oriented on the development of new depolymerization/degradation approaches using microwaves. These topics are important for reduction of the environmental footprint of polymers and to facilitate the transition towards a low-carbon society and sustainable, circular economy.
Significance for science
All proposed topics of the programme go beyond the current state-of-the-art and address some of the very current challenges in polymer science as follows: Polypeptide-based hybrid block copolymers have received great interest in material science since they offer a possibility to synergistically integrate the properties and functions of biomacromolecules and synthetic polymers in a single hybrid material. The enhanced possibilities given for the highly precise synthesis of such hybrid polymers provide new and unique opportunities to control the structure and final properties of these materials, which opens up new challenges in diverse areas such as nanotechnology (biosensors or medical diagnostics) and biotechnology (drug delivery systems, tissue engineering or implants). Design and synthesis of polypeptide-based hybrid block copolymers constitute nowadays a highly dynamic field since new applications and properties are sought out for such hybrid materials. In this programme we propose a simple one-pot synthesis to polypeptide-based hybrid block copolymers by a sequential addition of monomers which differ not only in reactivity but also propagate through the different end-group types, which is a major challenge in polymer chemistry. We expect that this synthetic approach will significantly simplify the preparation of well-defined polypeptide-based hybrid block copolymers, and consequently, such materials will be more easily accessible, giving them the opportunity to fulfill their high potential in various applications. Emulsion-templated synthetic polypeptide-based scaffolds disclose a promising alternative to currently available 3D scaffolds for cell culturing, tissue engineering and regenerative medicine as they offer clear benefits by combining the morphological features of polyHIPE materials with the unique properties of synthetic polypeptides, a combination that is an unsolved challenge yet. The resulting biomimetic, high performance synthetic polypeptide-based polyHIPE scaffolds represent advanced polymeric scaffolds hitherto unexplored. Such scaffolds will integrate all the important properties in a single material needed to create functional and implantable, biodegradable scaffold, and as such they will represent a new generation of biocompatible and biodegradable macroporous scaffolds. The results expected from the proposed research topic will be relevant to the development of polymer science since polyHIPE scaffolds based on synthetic polypeptides are intended to be prepared by a new synthetic methodology involving ring opening polymerization (ROP) of N-carboxyanhydrides monomers within a continuous phase of the high internal phase (HIP) emulsions which has not been tackled yet, and remains a major challenge to polymer scientists. We expect that findings acquired during the project execution will be, due to multidisciplinary aspect of the topic, relevant also to colloid, material, and biochemistry scientific communities. Aliphatic polyesters, distinguished by biodegradability, biocompatibility, and good mechanical properties, have recently received increasing attention in applications demanding biodegradable substitutes for conventional commodity thermoplastics, and in the biomedical field. While the physical properties of polyesters can be tailored via the chemical composition and architecture, the property profile of conventional polyesters lacking functionality such that their broader use in diverse applications is largely limited. The introduction of functional groups in the polyester backbone via ROP represents a new approach to engineer the material properties which will importantly contribute to the overarching goal in contemporary polymer research. To this end, we identify new chemical transformations of biobased levulinic acid into the new bioderived functionalized lactone/lactide monomers in order to synthesize advanced functionalized aliphatic (co)polyesters as the novel sustainable polymer materials that
Significance for the country
The potential impact on economic development: participation in creating new products, technologies, technology solutions, innovations The results acquired during programme implementation will have beside a novel scientific value also the applied nature and thus will offer an opportunity to further them toward higher TRL levels through advanced national or international projects or for direct transfer. For example, degradable macroporous scaffolds with well-defined morphology and functionality follow the demands for new materials and technologies in biomedical applications, especially for cell culturing, tissue engineering and regenerative medicine. On the other hand, macroporous nanocomposite photocatalysts might have a great market potential due to an economically attractive process of waste-water treatment. Research on the modification of nanocellulose and development of the processes for the preparation of their nanocomposites with improved properties can enable companies in the automotive, aerospace, electronics, consumer products, and medical device industries to develop new technological solutions and products with higher added value to gain better market position with these innovative materials.   The potential impact on social and cultural development Interest in the presence of plastic particles in environmental media (soil, air and water) and their effect on biota and human health is increasing among scientists, as is concern among the general public and policy makers. Therefore, human health and environmental impacts of micro and nano plastic pollution will be dealt with a great care to create conclusions supported by relevant scientific experiments and results. Emulsion-templated synthetic polypeptide-based scaffolds for cell culturing, tissue engineering and regenerative medicine as well as highly porous nanocomposite polyHIPE photocatalysts address some pivotal challenges of modern society, i.e. health care and water remediation, so successful implementation of the set goals could also have a strong impact on the society over a longer time period. Novel biobased and biodegeradable polymeric materials like functionalized aliphatic (co)polyesters with the new product design development and possibility of non-renewable materials replacement have a goal of overall higher sustainability in polymer use. On the other hand, the aim of cutting-edge recycling processes is targeting on the full reuse of difficult to recycle materials and recycling of valuable polymer systems to obtain virgin-like materials or feedstocks and undamaged fibers (e.g. carbon) as the best end-of-life option. These topics are important for reduction of the environmental footprint of polymers and to facilitate the transition towards a low-carbon society and sustainable, circular economy. All topics will also contribute to training of young researchers with competences in advanced high-tech and sustainable materials that are required by society and economy. The applied nature of research will result not only in applications and economic opportunities, but also in human resources development, and jobs.
