摘　　要：近年来,废弃碳纤维复合材料数量急剧增加,对人类的生存环境造成了严重破坏。为了实现废弃复材中树脂的高值化利用,本研究采用一步碳化法制备了废弃树脂基碳材料,研究了碳化温度对碳材料结构与性能的影响,并将碳材料制备成超级电容器电极,研究电极的电化学性能。分别采用扫描电子显微镜(SEM)、比表面积测试仪、傅里叶红外光谱仪(FTIR)、X射线光电子能谱(XPS)、拉曼测试仪(Raman)、差示扫描量热仪(DSC)和热重分析仪(TGA)对碳材料的表面形貌、孔性能、化学组分、石墨化程度以及形成原理进行了分析。结果表明:当碳化温度为800℃时制备的碳材料具有分级多孔的结构,孔性能和石墨化程度达到最佳,所制备的超级电容器电极表现出优异的电化学性能,在1 A/g电流密度下比电容高达299 F/g,经10000次充放电循环后,比电容仍高达296.6 F/g,循环稳定性优异。Recently,the number of waste carbon fiber composites has been increasing rapidly,which causes serious damage to human living environment.In order to realize the high-value utilization of resin in waste composites,in this research,waste resin-based carbon materials were prepared by one-step carbonization method.And the effects of carbonization temperature on the structure and properties of carbon materials were studied.Meanwhile,the electrochemical performance of supercapacitor electrodes prepared by the carbon materials was investigated.The surface morphology,pore properties,chemical composition,graphitization degree and formation principle of carbon materials were analyzed by scanning electron microscope(SEM),specific surface area tester,fourier infrared spectrometer(FTIR),X-ray photoelectron spectroscopy(XPS),Raman tester(Raman),differential scanning calorimeter(DSC)and thermogravimetric analyzer(TGA),respectively.The results showed that the carbon material possesses a hierarchical porous structure,and the pore properties and graphitization degree are the best under a carbonization temperature at 800℃.And the prepared supercapacitor electrode shows excellent electrochemical performances.The specific capacitance is as high as 299 F/g under the current density of 1 A/g,and it is as high as 296.6 F/g after 10000 charge and discharge cycles,which indicates an excellent cycling stability.
