摘要
以微米级聚丙烯腈短切纤维为原料,经过预氧化、碳化处理后得到聚丙烯腈基碳纤维电极材料。通过XRD测试对聚丙烯腈预氧化纤维预氧化程度进行了表征,用循环伏安法测试了碳纤维电极材料的电容性能,并采用正交试验法研究了聚丙烯腈基碳纤维电极材料较佳的制备工艺。正交试验及验证试验表明,当预氧化温度为240℃、预氧化时间为90 min、碳化温度为800℃、碳化时间为150 min时,得到的聚丙烯腈基碳纤维电极材料电容性能最佳,循环伏安测试(扫描速率为1 m V/s)其比电容值达到236.71 F/g。
In this paper, short-cut polyacrylonitrile micron fiber was used as raw material to prepare carbon fiber electrode materials. Short-cut polyacrylonitrile micron fiber was treated by preoxidation and carbonization to prepare polyacrylonitrile based activated carbon fibers electrode materials. The characterization of the carbon fiber electrode materials was studied by using X-ray diffraction （ XRD ） and cyclic vohammetry （ CV ）. Study on better preparation process of potyacrylonitrile based carbon fiber electrode materials by orthogonal test. The orthogonal test results show that the specific capacitance （236. 71 F/g at scan rate 1 mV/s ） of carbon fiber electrode materials is obtained at preoxidation temperature is 240 ℃, preoxidation time is 90 min, carbonization temperature is 800 ℃, carbonization time is 150 min.
