聚?咯為一本質導電高分子，利用其共軛的結構以傳導電子，達到導電的目的。然而聚?咯本身為極容易吸水的脆性物質，對環境安定度、熱穩定性均不及一般高分子；因此，添加無機材－蒙脫土除了能增強熱穩定性外，亦能提高機械強度。此外，當聚?咯－蒙脫土複合材料達到奈米級分布時，相較於傳統複合材料的形式，有較高之導電度。本實驗研究目的為探討聚?咯－蒙脫土奈米複合材料之製備方法，以及各種不同製程之導電度、熱穩定和熱機械性質量測。 Polypyrrole is the intrinsic conducting polymer with conjugated structure to transport electrons for conductivity. However polypyrrole has the deficiency of being brittle, water absorbing and environmentally, thermally unstable. One way to resolve these problem is by adding inorganic material（montmorillonite）,which can not only enhance thermal stability but also improve mechanical intensity. Furthermore, when the composite is mixed in nanoscale, more electrical conductivity may be obtained than the traditional composites. In this study, we probed into polypyrrole－montmorillonite nanocomposite preparation method. Electrical conductivity, thermal stability, and thermal mechanical properties were also investigated.
