We investigate on the synthesis of temperature and pH-sensitive hybrid microgels containing ZnO nanoparticles. The synthesis of ZnO nanoparticles was carried out in the presence of poly(N-vinylcaprolactum-co-acetoacetoxyethylmethacrylate-co-N-[3-dimethylamino)propyl] methacryl amide)(VCL/AAEM/PDMAPMAm) and it was observed that these microgels act as the container for deposition of ZnO nanoparticles, under the specific reaction conditions, leading to the formation of hybrid microgels. A close relationship between changes in properties of microgels and the loaded ZnO content was reported. Microscopic studies confirmed the inclusion of nanoparticles into microgels. It has been found that prepared microgels have tendency to form composite films on solid substrates after water evaporation, with homogenous distribution of ZnO nanoparticles in polymer matrix.
