摘　　要：以甲基丙烯酸甲酯和丙烯酸丁酯共聚物P(MMA-co-BA)乳液为基体,采用原位乳液聚合法制备了透明导电丙烯酸酯共聚物/聚苯胺(P(MMA-co-BA)/PANI)复合膜,并对制备工艺中苯胺的用量进行了探讨.使用紫外可见分光光度计对复合膜的透光性进行了分析,研究表明当苯胺浓度为0.25g/L时,复合膜的透光性较好,随苯胺用量的增加,复合膜的透光性下降,同时导致膜的吸水率上升,膜的耐水性变差.使用高阻抗测量仪和热重分析仪对复合膜的表面电阻及热稳定性进行了研究,使用傅立叶红外分光光度计、扫描电子显微镜对P(MMAco-BA)/PANI复合膜的结构进行了表征.A In this paper, methyl methacrylate and butyl acrylate copolymer （P （MMA-co- BA）） emulsion were used as the matrix to prepared the transparent and conductive compos- ite films of P（MMA-co-BA）/polyanitine （P（MMA-co-BA）/PANI）, the quantity of aniline was discussed. The transparency of P（MMA-co BA）/PANI films were analysised by using UV-vis spectroscopy, the transmittance of visible light was better with the concentration of aniline at 0.25 g/L, but the transparency and water resisting property were decreased with the increasing of aniline. Moreover, the resulting composite films were characterized by using high impedance measuring instrument, Fourier transform IR spectroscopy, thermogravimet- ric analysis, and scanning electron microscopy.
