    • 本研究分為兩個部分，主要是將一般常見的高分子母材(NBR橡膠)與導電高分子摻合，並且將後續的產物加入導電碳黑進行後處理，來探討這兩個處理方式而得到的樣品的機械性質、熱穩定性以及其電學特性。
    首先，關於高分子母材(NBR橡膠)與導電高分子摻合的研究方面，我們在高分子母材中合成出不同比例的PPy粒子的樣品，並且由這些不同比例的樣品來探討中含有不同比例的PPy粒子的母材的機械性質、熱穩定性以及其電學特性；而關於加入導電進行後處理，也是藉由不同比例的碳黑混合前段PPy處理的母材，來探討其相關的機械性質、熱穩定性以及其電學特性。
    從實驗結果可以得到一些較特殊的結論，在導電率方面，母材的硫化對電子導電是具有幫助的；對單獨反應PPy的NBR橡膠系統來說，添加11 wt.%的PPy可以得到最好的導電率，碳黑複合化NBR橡膠系統，則是需添加到20 wt.%才有較明顯且最好的複合效果；熱穩定性方面，加入碳黑對於整體母材的耐熱性上是具有提升的效果；從SEM圖可看到在NBR橡膠所分佈的PPy和碳黑粒子，均有團聚的現象發生。

    The two purposes of the research including combining conducting polymer and conventional polymer, and performing carbon black modification to the pre-processing blends, to investigate the influence on mechanical properties, thermal stability, and electrical properties of the sample.
    In the first place, in the aspect of the research of the combining conducting polymer and conventional polymer, various ratios of PPy to NBR rubber, investigate the influence on the mechanical properties, thermal stability, and electrical properties caused by synthesizing various ratios of PPy. In the other aspect of the research of the performing carbon black modification to the pre-processing blends, various ratios of carbon black were mixed with the pre-processing blends in the internal mixer, to investigate the influence on the mechanical properties, thermal stability, and electrical properties caused by mixing various ratios of carbon black.
    As a result, we know that the conductivity of the vulcanized blends is higher than that of non-vulcanized blends of both components; the conductivity of PPy blends is highest at the content of 11 wt.% PPy, and the conductivity of PPy/carbon black blends were higest at the content of 20 wt.% carbon black; the thermal properties was increased with increasing in carbon black content; the SEM indicated that the morphology of PPy and carbon black was achieved in the form of spherical and irregular by mechanical mixing. On the other hand, we can find that there is an agglomerate of PPy and carbon black in NBR.
