【摘要】 研究了石墨—聚苯乙烯—苯、石墨—醇酸清漆—稀释剂、石墨—硝基清漆—稀释剂 3种涂料中分别掺入碘后对涂料导电性能的影响 .实验表明 ,掺碘后 3种涂料的导电性分别提高到3.1倍、4.5倍、1 3.1倍 .其增导机理有 :一是生成石墨—碘传荷络合物 ,二是碘与聚合物反应生成了极性基团 .在相同情况下 ,溶液型涂料导电性高于溶胶型涂料 .更多还原

【Abstract】 The I 2-doping effects on the electric conductivities of three kinds of paints:Graphite-polystyrene-benzene,Graphite-alcohol acid Varnish-dilute and Graphite-nitro-Varnish-dilute is studied.After being I 2-doping, the electric conductivity of three paints are raised 3.1,4.5,13.1 times respectively.The increased conduction mechanism is that:(1)the graphite-iodine charge transfer complex is produced;(2)the iodine reacts with polymer to produce the polar group.Under the same condition,the conduction of the solution paint is stronger than the sol paint.更多还原
