摘　　要：本文对偶联剂处理碳纤维前后纤维表面基团的变化进行了分析,并就偶联剂处理碳纤维对碳纤维纸性能的影响进行了研究,结果表明:处理后,碳纤维表面的羟基和含氧基团的数量增多,在偶联剂用量为2%时,碳纤维纸的性能较优,此条件下的碳纤维纸透气性、强度性能优于未经处理的碳纤维纸,但导电性能有所下降。In this paper, the effect of coupling agent on the surface group of carbon fiber and its effect on the performance of carbon paper were analyzed. The results showed that the amount of hydroxy and oxygen-containing groups increased after the fiber being treated ; the optimum properties were obtained when the dosage of coupling a- gent was 2%. At this condition, compared with the untreated carbon fiber paper, the porosity and strength of the treated paper increased, but the conductance decreased.
