Intrinsically conducting polymers (ICP), e.g. polyaniline, polypyrrole, attract considerable attention due to their unique complex of physical and chemical properties, which allows their applications in different high-tech fields [1]. An our research is focused on the synthesis and investigations of new ternary core-shell composites of polystyrene (PS)-poly-N-isopropylacrylamide (PNIPAM) nano- and micro-sized particles with polyaniline or pyrrole. These composites were synthesized by the chemical oxidative polymerization of aniline or pyrrole in PS-PNIPAM latex environment. The chemical composition of the resulting composites was determined by UV-Vis and FTIR- spectroscopy. The morphology as well as particles size were proved with dynamic light scattering (DLS) and transmition electron microscopy (TEM). The thermal sensitivity of the composites was proved.
It was found that these nanocomposites are not conductive but some conductivity was recognized after an exposure in HCl that suggests their applications as sensor materials.
