【摘要】 采用相分离原位聚合法制备了聚苯胺/聚砜(PANI/PSF)复合膜,结果表明,复合膜的正面(与溶液接触的一面)是绿色的,而反面是白色的.复合膜的表面形态和化学组分用FT-IR和SEM进行了表征,探讨了温度、时间、反应剂浓度对复合膜电阻的影响,热重分析显示,PANI/PSF复合膜的热稳定性高于纯的聚砜膜.更多还原

【Abstract】 Polyaniline(PANI)/polysulfone(PSF)composite films are successfully prepared by phase separation and one-step in-situ polymerization.It is found that the head-on face(in contact with solution)of the films is green while the back face is white.The chemical component and the surface morphology of both surfaces of the films are characterized by FT-IR spectra and SEM,respectively.The effect of the polymerization temperature,time and concentration of the reactants on the electrical properties of the films are discussed in details.The thermo-oxidative degradation of the films is studied by thermogravimetric analysis(TGA).The results indicate that the thermal stability of the PANI/PSF films is higher than that of the pure PSF film.更多还原
