摘要

采用溶胶-凝胶（sol-gel）法，将正硅酸乙酯和水加入到制备聚对苯二甲酸乙二酯（PET）的中间产物对苯二甲酸双羟乙酯(BHET)中

在液态下均匀混合，高温下快速发生溶胶-凝胶反应，再按PET缩聚反应制得PET/SiO2纳米复合材料。通过TEM、TG、DSC对材料进行了表征和研究。结果表明，SiO2在PET中均匀分散，其尺寸在10～100 nm之间，PET/SiO2纳米复合材料的热降解活化能较普通PET有明显提高，但初始降解温度和结晶性能均有所降低。

Abstract

Poly(ethylene terephthalate)(PET)/SiO2 nanocomposites were synthesized via the sol-gel method that involved two steps: terephthalic acid first reacted with excess ethylene glycol to form bis(hydroxyethyl) terephthalate (BHET); tetraethoxysilane (TEOS) was added into the BHET

and the sol-gel reactions proceeded at a high temperature to form the silica nanonetwork concurrent with polycondensation of BHET to produce the PET matrix.Transmission electron microscopy (TEM) showed that the sizes of silica particles were at nanoscale

and the nanoparticles were uniformly dispersed in the polymer matrix.Thermogravimetric analysis (TGA) results indicated that the activation energy of thermal degradation of the composites was largely increased.The nonisothermal crystallization ability of the composites was found to decrease according to differential scanning calorimetry (DSC).
