                 摘要:采用改良的分步液相原位聚合法使得聚苯胺均匀生长在碳纤维纸基体上。考察了碳纤维质量分数、引发
                 剂过硫酸铵(APS)与苯胺用量,以及浸渍时间和反应时间对聚苯胺-碳纤维导电纸导电性能的影响。采用 SEM
                 观察导电纸的微观形貌,利用 FTIR 与 EDS 分别表征其表面结构与元素变化。结果表明,当碳纤维质量分数为
                 20%,引发剂 APS 浓度为 0.375 mol/L,n(苯胺)∶n(盐酸,1 mol/L)=2∶1,反应时间为 12 h,浸渍时间为 1 min
                 时,制备的导电纸(PANI-CP)的导电性能最佳。相对于碳纤维原纸(CP),制备的 PANI-CP 电导率为 5.435 S/cm,
                 导电性能提高 250.0%,抗张指数为 27.665 N·m/g,抗张指数提高 37.3%。相对于液相原位聚合法制备的导电纸
                 (L-PANI-CP),PANI-CP 导电性能提高 85.9%,总色差值(DE)下降 66.0%。

                 Abstract: The modified stepwise liquid phase in-situ polymerization method was used to make polyaniline
                 grow uniformly on the carbon  fiber paper substrate. The effects  of carbon fiber mass fraction, initiator
                 ammonium persulfate (APS) dosage, aniline dosage, dipping time and reaction time on the conductivity of
                 polyaniline-carbon fiber conductive  paper were investigated. The morphology, surface structure and
                 element changes of conductive paper was characterized by SEM, FTIR and EDS. The results showed that
                 under the conditions of mass fraction of carbon fiber of 20%, APS concentration of 0.375 mol/L, n(aniline)∶
                 n(hydrochloric acid,  1 mol/L)=2∶1, reaction time of  12 h and immersion time of  1 min, the  prepared
                 conductive paper (PANI-CP) had the best conductivity. Compared with those of carbon fiber base paper
                 (CP), the conductivity of PANI-CP was 5.435 S/cm, which was an improvement of 250.0%, the tensile
                 index was 27.665 N·m/g, and the physical strength increased by 37.3%. Compared with the conductive
                 paper (L-PANI-CP) prepared by liquid phase in-situ polymerization method, the conductivity of PANI-CP
                 was increased by 85.9% and the total color difference DE decreased by 66.0%.
