研究了碳材料表面功能化对超级电容器电极用碳/聚合物复合材料形貌和性能的影响。通过对碳纤维进行简单的化学改性，制备了氧化碳纤维（OCF）、氨基功能化碳纤维（AFCF）和胺化三嗪功能化碳纤维（ATFCF）。在此基础上，采用电化学原位聚合法制备了聚苯胺/碳纤维纳米复合材料（PANI/OCF，PANI/AFCF，PANI/ATFCF）。通过FTIR、拉曼光谱和SEM研究了聚苯胺/碳纤维复合材料的化学组成和形貌。结果表明，由于聚苯胺与OCF之间的非共价键连接，使得OCF复合材料上的聚苯胺呈现出无序的层状结构。相反，聚苯胺生长在AFCF和ATFCF的表面上的有序的方式，由于化学共价连接，表现出纳米线阵列和花瓣状纳米片，分别。这表明通过对碳纤维表面官能团的分子结构设计可以有效地调控PANI/CFs复合材料的形貌。利用电化学工作站对PANI/CF复合材料的电化学性能进行了评价。与非共价键PANI/OCF复合材料相比，PANI/AFCF和PANI/ATFCF复合材料的共价键相互作用以及有序的纳米结构有利于更快的电荷转移、更小的内阻和更好的力学性能，从而提高了电化学性能。
The effect of surface functionalization of carbon materials on the morphology and performance of carbon/polymer composite materials for supercapacitor electrodes was investigated here. Three kinds of functionalized carbon fibers were prepared by the simple chemical modification of carbon fiber, named oxidated carbon fiber (OCF), amino-functionalized carbon fiber (AFCF) and aminated triazine functionalized carbon fiber (ATFCF). Then functionalized carbon fibers were used to fabricate nanostructural polyaniline/CFs composites (PANI/OCF, PANI/AFCF, PANI/ATFCF) by electrochemical in situ polymerization under pulse current. The chemical compositions and morphologies of these PANI/CFs composites were studied by FTIR, Raman spectra and SEM. It was found that PANI on OCF composites displayed a disordered nanofiber structure owing to the non-covalent connection between PANI with OCF. Conversely, PANI grew on the surface of AFCF and ATFCF in an ordered fashion due to chemically covalent connection, exhibiting nanowire arrays and petal-like nanosheets, respectively. It hints that the morphology of PANI/CFs composites can be effectively adjusted by molecular structural design of functional groups on the functionalized CF. The electrochemical properties of these PANI/CF composites were evaluated by an electrochemical workstation. In comparison with noncovalent PANI/OCF composites, the strong covalent interactions together with the ordered nanostructures of PANI/AFCF and PANI/ATFCF facilitated faster charge transfer, smaller internal resistance and better mechanical properties, resulting in improved electrochemical performance.
