In the present study, spherical nanoparticles (NPs) containing polyhedral oligosilsesquioxane (POSS) as an inner hydrophobic core and poly(vinyl alcohol) PVA as a hydrophilic outer shell were prepared by dialysis approach. Preparation of amphiphilic POSS-grafted-PVA co-polymer was characterized by 1 H NMR and FT-IR. The results indicated urethane linkage between monoisocyanate group of POSS...
We report the effect of gold nanoparticles encapsulated into the shell-forming PAMAM dendrimers on the assembly and properties of multilayer microshells. We demonstrate that the PAMAM-encapsulated gold nanoparticles change dramatically the optical spectroscopic properties of microcapsule dispersions, without significantly affecting the stiffness of microcapsules. Our results indicate that the use...
