高分子半导体(polymerconductor)。指电导率介于导体和绝缘体之间的高分子材料，根据材料的组成划分，包括复合型半导体高分子材料和结构型半导体高分子，在后一种材料中一般都含有线性共轭分子结构，导电方式以电子导电为主。π电子的离域性构成了导电性质， 
分子轨道间的能级差，使其导电能力处在半导体范围。经过掺杂处理之后半导体高分子材料的导电能力往往可以大幅度提高，从半导体进入导体范围。
Polymer conductor. It refers to the polymer material withconductivity between conductor and insulator. According to thecomposition of the material, it includes composite semiconductorpolymer material and structural semiconductor polymer. The lattermaterial generally contains linear conjugated molecular structure,and the conduction mode is mainly electronic conduction.
The delocalization of π electrons constitutes the conductivity.The energy level difference between molecular orbitals makes itsconductivity in the semiconductor range. After doping, theconductivity of semiconductor polymer materials can often begreatly improved, from semiconductors to conductors.
