摘要
以吡咯单体的水溶液为原料,氯化铁为引发剂,利用原位聚合法在玻璃纤维板表面生成一层聚吡咯(PPy)薄膜。探讨了吡咯单体浓度、聚合温度、聚合时间、聚合pH值、引发剂用量5个工艺条件对PPy膜电导率的影响。结果表明制得高电导率的工艺条件为:吡咯单体浓度0.041mol·L-1,温度20℃,FeCl3·6H2O 3.13g,pH值为2.6,聚合20min;电导率最好可达9.259S·m-1。在该工艺下得到的PPy膜的电导率随时间变化的规律,发现电导率基本不变,稳定性很好。
A layer of polypyrrole（PPy）film was polymerized on the surface of glass fiber,using aqueous solution of pyrrole monomer as raw materials, FeCl3 as an initiator. The effects of the pyrrole concentration, polymerization tempera- ture,polymerization time,polymerization pH and the amount of initiator on the conductivity of PPy film were investigated. The results showed that the optimal conditions for a high conductivity were follows： pyrrole monomer concentration 0. 041mol · L^-1 ,temperature 20℃ ,FeCl3 · 6H2O3.13 g,pH 2.6, polymerization 20min. The best conductivity of PPy film reached to 9. 259 S · m^-1 . The variation of conductivity with time was also investigated and the conductivity was found substantially unchanged,at the same time the stability of fime were well.
