摘要： 以聚醚砜(PES)为基体,通过溶胶-凝胶过程,得到了分散均匀的PES/SiO2杂化材料,用扫描电镜、透射电镜、傅里叶红外及差示扫描量热法研究不同SiO2含量的PES/SiO2杂化材料材料性能.结果表明,当PES/SiO2杂化材料中SiO2的质量分数大于10%时可获得有机聚合物链段与无机网络互穿的均匀分散的复合材料.此材料的玻璃化转变温度(Tg)明显提高.

Abstract: The different polyethersulphone(PES)/SiO2 hybrids were prepared by sol-gel method. The sample were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray diffraction(XRD), Fourier transformed infrared spectrum(FTIR) and differential scanning calorimetry(DSC). The results showed that PES/SiO2 composites in nanoscale with the construction of hybrid organic-inorganic networks were prepared by sol-gle method when the content of SiO2 was more than 10%. The T g of hybrids was improved.

Key words: Polyethersulphone, Sol-gel process, Hybrids, n-Ethyl silicate
