摘　　要：电极材料的比表面积、孔道结构及孔径分布、杂原子等都是影响超级电容性能的重要因素。本研究以间氨基苯酚为原料,与甲醛反应制备聚苯并噁嗪微球(APFs),经KOH活化处理并高温炭化后,得到能够用于超级电容器的含杂原子多孔炭。采用SEM、BET、XRD和XPS等对样品的形貌、比表面积、石墨化程度和表面官能团进行测定,并借助循环伏安法、恒电流充放电测试法和交流阻抗法对样品的电化学性能进行探究。结果表明,所制备的CAPFs-700-2材料具有丰富的孔道结构,且比表面积高达3188 m^(2)/g。此外,CAPFs-700-2表现出优异的超级电容性能,在电流密度为0.5 A/g时其比电容达到228 F/g,在5000次循环后其比电容保持率仍为90.2%,表现出良好的倍率性能和循环稳定性。The specific surface area,pore structure,pore size distribution and heteroatoms of electrode materials are important factors affecting the supercapacitive performance.In this study,Poly(benzoxazine)microspheres(APFs)were prepared by m-aminophenol and formaldehyde,after activation of KOH and carbonization at a high temperature,the porous carbon with heteroatoms for supercapacitors were obtained.SEM,BET,XRD and XPS were used to characterize the morphology,specific surface area,graphitization degree and surface functional groups of the samples.Cyclic voltammetry,galvanostatic charge-discharge tests and AC impedance method were used to investigate the electrochemical properties of the samples.The results showed that CAPFs-700-2 has a rich pore structure with the specific surface area of 3188 m^(2)/g.Furthermore,CAPFs-700-2 exhibits excellent supercapacitor property with the specific capacitance of 228 F/g at the current density of 0.5 A/g.After cycling 5000 times,its specific capacitance retention rate is 90.2%,which possesses high rate performance and cycle stability.
