Polysulfone (PSU) is well known as the engineering plastic with high thermal stability, mechanical strength, and biocompatibility. PSU has been used as the membranes for microfiltration (MF), ultrafiltration (UF), and gas separation (GS) by diverse methods. To overcome the defect which in the hydrophobicity of PSU, hydrophilic materials have been used to blend or copolymerize with PSU. In this work, polyethylene glycol (PEG) was used as the bridging group of bridged polysilsesquioxane (BPS) with various ratios. BPS monomer was synthesized of PEG and isocyanate-functionalized silane. PEG-based BPS nanoparticles (NPs) were fabricated by Stöber process of BPS monomer with polymeric bridging group. They have excellent biocompatibility, thermal stability, durability, and elasticity. Properties of PSU membrane containing PEG-based BPS NPs were characterized by FT-IR, NMR, SEM, and various instruments. |
