Patent invention belongs to the field of processes for preparing conductive Ag/PANI nanocomposites using functional alkoxysilanes as capping agents. This process allows formations of nanostructures of homogenous sizes and morphology with conductive characteristics in range between 0,02 and 0,003 S/cm, with process being performed at low reaction temperatures and with use of environmentally friendly chemicals. Compared to so far known preparation processes, this process differs from them, that the preparation process involves synthesis of silver nanoparticles with new agent for limiting growth and that silver nanoparticles are homogenously distributed through polymer matrix, as polymerization in acidic medium occurs simultaneously with silver nanoparticles incorporation thus improving its conductivity.

COBISS.SI-ID: 20419606The present invention belongs to the field of processes for preparation of antimicrobial nanoparticles, more particularly to the field of processes for preparation of antimicrobial copper nanoparticles which include functional alkoxysilanes, preferably aminopropyltrimethoxysilane (APTMS) as precursors, which function as capping agents. The essence of the synthesis process of copper nanoparticles is in that it includes high-temperature polyol synthesis based on organic based colloidal solution of copper nanoparticles with the average particle size in the range from 5 nm to 170 nm using functional trialkoxysilane molecules as capping agents (which limit particle growth). Antimicrobial copper nanoparticles prepared according to the synthesis process have a wide spectrum of use, for example as bactericides in paints or plasters for hospital equipment, in medical instruments and devices, in preparation of textiles with antimicrobial properties, in water treatment, in food processing as well as in objects and equipment in public spaces, public transportation, paints, toys, kitchens and hospital utensils.

COBISS.SI-ID: 301275136The present invention belongs to the field of processes for preparing nanostructures, more precisely to the field of processes for preparing homogeneous superparamagnetic hollow spherical nanostructures with a porous shell based on iron oxide. The technical problem, which is solved by the invention, is the design of a process for preparing hollow magnetic spherical nanostructures based on coating of solid silicon dioxide cores with magnetic nanoparticles of iron oxide in a spinel crystal structure and formation of hollow spheres using appropriate buffer solutions. The essence of the process for synthesis of superparamagnetic hollow spherical nanostructures is that it includes adsorption of Fe 2+/Fe 3+ ions onto the surface of mono-dispersed silicon dioxide (SiO 2 ) solidtemplates, pre-prepared by the Stöber process, and dissolution of SiO 2 solid-templates by the use of basic aqueous solutions of [2OH -/HCO 3 - ] ions and [CO 3 2-/HCO 3 - ] ions having pH value between 7 and 12, and reaction of precipitation of Fe 2+/Fe 3+ ions in the form of superparamagnetic spinel iron oxide nanoparticles. Thus obtained superparamagnetic hollow spherical nanostructures enable responsiveness and manoeuvrability of the whole nanostructure using external magnetic field, as well as the local release of loaded active substances due to the porosity of the superparamagnetic shell.
