导电性高分子化合物的必要条件

高分子导体作为新型导电材料的出现,引起人们对它的广泛注意。本文主要通过对一些新近的实验结果(数据)的分析,综述了高分子化合物导电的必要条件。即,高分子导电性的大小决定于体系中π电子轨道(2Pz轨道)重叠的程度。并且叙述了高分子主链的化学结构与高分子化合物导体的导电性关系。高分子共轭体系中具有链均一性,具有较短共轭长度,以及分子平面不发生扭曲的情况,其导电性较高。

The Necessary Condition of Electroconductivity of Conducting Polymers

The emergence of conducting polymers as a new subject of electronic materials has attracted considerable attention. In this article, by analyzing some of the recent experimental results ( data ), the author summarized that the necessary condition of electro conductivity of Conducting polymers is its dependence on π-electronic orbital overlaps.The author also described the relationship between Chemical structure of the parent Chains and electroconductivity of Conducting polymers. If the Chemical structure is of the uniformity of the polymers Chains with Short Conjugated length and the plane of polymers doesn't twist, The eleclroconductivity Can be improved.
