摘要
借助于傅里叶红外光谱和电位滴定分析,研究了热解炭氧化前后表面含氧基团组成的变化以及氧化温度和氧化时间对热解炭表面含氧基团组成的影响。研究结果表明,热解炭表面的各种含氧基团随着氧化温度的升高和氧化时间的延长而增加,热解炭表面残留的脂肪基团减少。在不过度降低热解炭粉强度的情况下,在80℃下氧化处理2h可达到满意的氧化效果。
The composition changes of surface with oxygen-containing groups of pyrolytic carbon before and after oxidation and the influence of oxidation temperature and time on the composition of oxygen-containing groups of the pyrolytic carbon surface are studied by means of Fourier infrared spectrum and potentiometric titration.The results show that the surface oxygen-containing groups increase and the surface fatty group decrease along with the rise of oxidation temperature and the prolongation of oxidation time.In order to keep the strength of the pyrolytic carbon powder,the acceptable oxidation condition is that the oxidation temperature and time are 80℃ and 2 hours respectively.
