In adding - acid system : the resistivities of different lithotypes “ cp tend towards being constant and equal when weight percentage of aniline exceeds 50 % ; because of the structure difference of different lithotypes , the polymerizing places and processes are different ; the resistivities of vituain / pan and fusain / pan reach the lowest point respectively when ( ntloisiog / an is 0 . 6 , 1 . 0 ; the resistivities of cp decline fast and tend towards being constant along with the reduction of diameter of coal . in not adding - acid system : the resistivities of different lithotypes ' cp decline evenly ; it is found on the crossed experiment of cp , that ( nflsaog / an mole proportion is the most important factor to influence output ratio of cp and the weight percentage of aniline is the most important factor to influence resistivities of cp . according to the result of the crossed experiment of cp 在有外加酸體系中:苯胺百分含量大于50時,不同煤巖組分的電阻率趨于恒定和一致;由于不同煤巖組分結構上的差異,導致苯胺聚合場所和聚合過程的不同;當過硫酸銨/苯胺摩爾比為0 . 6 , 1 . 0時,鏡煤-聚苯胺導電材料電阻率和絲炭-聚苯胺導電材料的電阻率分別達到最低值;在無外加酸體系中:不同煤巖組分/聚苯胺導電材料的電阻率隨著聚合時間的增加而均勻下降,并在8小時左右達到恒定;在對絲炭-聚苯胺導電材料進行的正交試驗中發現:過硫酸銨/苯胺摩爾比對產率的影響最大,苯胺重量百分比對產率影響最小,而對產物電阻率影響最大的是苯胺重量百分比。
