Polyethersulfone (PES) is well known as the engineering plastic with high thermal stability, mechanical strength, good transparency and biocompatibility. PES has been used to the membrane filters for microfiltration (MF), ultrafiltration (UF) and gas separation (GS) by various methods. To overcome the hydrophobicity of PES, hydrophilic materials have been used to blend or copolymerize with PES membrane or PES solution. In this works, PES or polyethylene glycol (PEG) was used as the bridging group of bridged polysilsesquioxane (BPS). BPS monomer was synthesized with PES or PEG and isocyanate-functionalized silane. BPS nanoparticles (NPs) were fabricated by Stöber process of BPS monomer with polymeric bridging group. BPS NPs have excellent biocompatibility, thermal stability, durability and elasticity. Properties of BPS NPs were characterized by FT-IR, NMR, SEM ,and various instruments.
