在有外加酸體系中:苯胺百分含量大於50時,不同煤巖組分的電阻率趨于恆定和一致;由於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,並在8小時左右達到恆定;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。This compound was firstly used as a fluorescence carrier of chemical sensors to examine the toxic p - nitroaniline. compared with conventional methods, this sensor has lower cost, wider detection range, higher sensitivity and selectivity, better reproducibility and reversibility. 4
