中文摘要：

研究了在环氧树脂塑料封装材料表面制备导电聚吡咯（PPy）薄膜的化学聚合方法，分析了影响聚吡咯薄膜微观形貌、附着力及电导率的因素。用四探针法测聚吡咯薄膜的电导率，并用扫描电子显微镜（SEM）、红外光谱（IR）、X射线光电子能谱（XPS）进行了表征。通过对电子封装材料的表面预处理与改性，制得了附着性好、均匀连续的聚吡咯薄膜，经掺杂电导率达到了45．10S／cm。

英文摘要：

Polypyrrole film was prepared on the surface of epoxy resin plastic electronic packaging materials by chemical polymerization method. Effect factors of micro-morphology, adhesion and conductivity of polypyrrole film were analyzed. The conductivity of PPy film was measured by the four-point probe method and the samples were characterized by scanning electron microscopy （SEM）, infrared spectrum （IR） and X-ray photoelectron spectroscopy （XPS）. A homogeneous and compact polypyrrole film was obtained through pretreatment and mod- ification by surfactant to the surface of electronic packaging,and the conductivity got to 45.10S/cm by doping.
