Nano particles of polystyrene and poly(butyl acrylate) were synthesized by emulsion polymerization technique using sodium dodecyl sulfate(SDS) and tetradecyltrimethylammoniumbromide(TTAB) as surfactant, respectively. PS/PBA polymer nanoparticles were hybridized with silica nanoparticles by electrostatic mixing in emulsion state. The blending of PS(SDS)/PBA(TTAB)/silica were controlled by concentration and composition. The composition of blend was characterized by 1H-NMR in CDCl3 solution. Morphology, optical clarity, thermal resistance and physical properties of PS/PBA/silica hybrids were investigated systematically by using SEM, UV-VIS, TGA and UTM, respecively. |
