摘要
采用磷化物水蒸汽结合处理法 ,对低模量聚丙烯腈基碳纤维及粘胶基碳纤维进行了重量损失 ,液相吸附实验。对各种影响因素进行正交优化设计、平行实验和线性回归处理 ,以亚甲基兰吸附量为指标 ,从而确定了最佳工艺参数。比表面积。
The weight loss and liquid phase absorbability of low modulus PAN carbon fibre and viscose carbon fibre after surface modified by the phosphide steam method were studied. Various influencing factors were investigated experimentally according to orthogonal design. Both fibres were tested parallelly and the data obtained were treated by linear regression. Based on the absorbed amount of methylene blue, the optimum modification parameters were determined. The structure of both fibres before and after surface activation were characterized by their specific surface area, pore size distribution and SEM micrographs.
