导电性的机理有机高分子化合物导电性差,所以通常将其作绝缘材料使用。这是因为形成有机高分子化合物骨架的碳原子,是以SP~3杂化轨道的电子结构构成碳-碳饱和键的缘故。饱和键的键能大且比较稳定,电子为此键所束缚,因而不能像金属的自由电子那样离开键自由移动,故不能导电。 Mechanism of Conductive Organic polymer compounds are poor in conductivity and are generally used as insulating materials. This is because the carbon atoms forming the skeleton of the organic polymer compound form a carbon-carbon saturated bond due to the electronic structure of the SP 3 hybrid orbital. Saturated bond key can be large and more stable, the electron is bound to the key, and therefore can not move away from the free metal as the free electrons, so it can not conduct electricity.
