摘　　要：利用化学滴定法分析阳极氧化PAN基HM炭纤维表面酸性官能团,结果发现:炭纤维表面酸性官能团随电流密度增大而明显增加,最终达到“饱和”。这将有利于进一步研究PAN基高模炭纤维氧化机理和粘结机理。The surface acidic functional groups of PAN-base HM CF were treated by anodie oxidation was determined by ehemieal titriment method. It was indicated the groups increased greatly,finally leveled off with the increase of applied current density. Those were beneficial to investigate the oxidation and adhesion mechanism of PAN-base HM CF.
