中文摘要：

聚芳醚砜类材料作为全芳香无定形耐高温工程塑料一直备受关注，在航空、航天、信息及能源等领域得到了广泛的应用．以脂肪族聚合物为基体的杂化材料往往不具备良好的热、化学与辐射稳定性．人们希望通过将无机粒子引入芳香性耐高温聚合物中，使其既具有理想的性能，又满足苛刻的运行环境．通过简单物理掺杂和共混的方法很难精确控制材料的微观形态号陛能．利用溶胶-凝胶法将无机相引入聚合物体系中，通过调节有机与无机的组分比可以实现对材料的“剪裁”，达到有机一无机两相最优组合的目的．

英文摘要：

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.
