Abstract

Polymer blends, composites as well as polymer membranes are the research subjects of this project. Compatibilizing effects of styrene/rubber block copolymers (SRBC) poly(styrene-b-butadiene-b-styrene) (SBS), poly(styrene-b-ethylene-co-propylene) (SEP), and two types of poly(styrene-b-ethylene-co-butylene-b-styrene) (SEBS) which differ in their molecular weights on morphology, mechanical properties, and processing properties of immiscible polypropylene/polystyrene (PP/PS) blends are studied. The role of styrene/rubber block copolymers on the interfacial changes of PP/talc composites is also investigated. Mechanisms of the asymmetric porous membrane formation by wet phase inversion are investigated. A specific mechanism is interpreted in terms of successive postulated elementary processes which are distinguished by observing membrane surface and cross section morphology and pure water permeability as well as turbidity and shrinkage phenomena of the cast solution after immersion into the nonsolvent coagulation bath. Recently introduced in our laboratory, a preparation of the double layered membranes may enables much clearer introspection into the elementary processes and consequently into the membrane formation mechanisms. Chemical modification of the surface of the polymeric asymmetric porous membranes with purpose of diminishing the concentration polarisation and membrane fauling during the membrane separation process is investigated. This study is also designed in order to introduce bioactive materials (antibody, enzyme, cell organelle, cell etc) on the surface of polymeric membranes and in this way to follow research directions of preparing basic elements for biosensors and bioreactors. The influence of surface conditions on defects in liquid crystal cell is studied. A distribution of small ions in the solution at the close proximity of polyelectrolyte shells and its influence on the equilibrium distribution of the ions across these selective permeable hollow shells are studied.
