摘　　要：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.A novel aromatic polyethersulfone bearing a（3-methoxy）phenyl group（PPES-OMe） was synthesized via an aromatic nucleophilic substitution reaction.
