摘　　要：通过测定不同条件下PVDF共混改性膜内无机组分含量的变化情况,以考察共混膜内无机组分的稳定性。并利用透射电镜观察改性膜中纳米颗粒的分布,探求无机组分在共混膜内的结合方式。实验结果表明,在PVDF膜的适用p H范围内,改性膜内的无机组分在溶液中基本可以保持含量稳定。利用透射电镜对改性膜进行观察得出,无机组分以纳米尺寸较均匀地包埋于高分子聚合物的内部。The stability of inorganic components in the PVDF blended modified membrane was investigated by testing the changes of inorganic component content under different rest conditions. Transmission Electron Microscopy （TEM） was employed to observe the distribution of nanoparticles in the modified membrane, which could help-explore the combining form of the inorganic components in the membrane. The results indicated that inorganic components were almost retained the stable content among the proper pH value. It was observed by TEM that the inorganic components in nano-size was evenly wrapped among the polymer.
