A novel aromatic polyethersulfone bearing a(3-methoxy)phenyl group(PPES-OMe)was synthesized via an aromatic nucleophilic substitution reaction.A hydroxyl-containing polyethersulfone(PPES-OH)was successfully obtained via a demethylation reaction of PPES-OMe.A series of nano-hybrid materials could be prepared with sol-gel method and FTIR results suggested the chemical bond formed between the hydroxyl group of PPES-OH and TEOS.Nano-size SiO2 particles were observed to disperse uniformly in the polyethersulfone matrix by SEM.It was found that all the films based on these materials were flexible.
