摘要
为进一步改善多孔炭材料的性能,以苯并噁嗪为前驱体,以氯化锌(ZnCl_(2))为活化剂,分别经过固化、预氧化、炭化和活化过程制备多孔炭材料。利用X射线衍射仪、元素分析仪、激光拉曼光谱仪、扫描电子显微镜、比表面及孔隙度仪和电化学测试对多孔炭材料的结构和性能进行表征。结果表明,苯并噁嗪基多孔炭材料的石墨化程度随着活化温度的升高逐渐提高。其比表面积、孔体积和孔径均先减小后增大,当活化温度为900℃时,多孔炭材料(C-900)的比表面积达到最大1112.33 m^(2)/g,此时比电容也最大,C-900的比容量为300 F/g,且具有良好的循环稳定性。所制备多孔炭材料性能优良,拓宽了苯并噁嗪树脂的应用范围。
In order to further improve the properties of porous carbon materials,the porous carbon materials were prepared through the processes of curing,pre-oxidation,carbonization and activation using benzoxazine as the precursor and zinc chloride(ZnCl_(2))as the activator.The structure and properties of the porous carbon materials were characterized by X-ray diffractometer,elemental analyzer,laser Raman spectrometer,scanning electron microscope,specific surface and porosity meter and electrochemical test.The results show that,with the increase of activation temperature,the graphitization degree of benzoxazine-based porous carbon increases gradually.The specific surface area,pore volume and pore size decrease first and then increase.When the activation temperature is 900℃,the specific surface area of the porous carbon(C-900)reaches the maximum of 1112.33 m^(2)/g.Meanwhile,the specific capacitance of C-900 attains the highest of 300 F/g with excellent cycle stability.The porous carbon material prepared by this method has excellent performance,which broadens the application range of benzoxazine resin.
