Preparation of PES-SiO_2 Hybrids Through Sol-gel Method

The different polyethersulphone(PES)/SiO 2 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/SiO 2 composites in nanoscale with the construction of hybrid organic-inorganic networks were prepared by sol-gle method when the content of SiO 2 was more than 10%. The T g of hybrids was improved.
