Abstract

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
