纳米ATO改性聚丙烯腈纤维的研究

Study on Polyacrylonitrile Fiber /Modified by Nano-ATO Particles

摘要: 采用高导电率的纳米粉体ATO(SnO2·Sb2O3)为抗静电剂,从6种不同类型的分散剂中筛选出聚乙烯亚胺,通过设计正交实验探索出最佳工艺组合,将纳米ATO稳定均匀地分散于去离子水中,将该悬浮液作为聚丙烯腈纤维纺丝过程的预热浴,来改善聚丙烯腈纤维的抗静电性,研究了ATO用量、添加位置等对纤维抗静电性能、力学性能的影响。

Abstract: A new method was invented to prepare novel antistatic PAN fiber. Nano-ATO particles were dispersed in water by dispersant PEI, which was used as pre-heating bath during the process of PAN fiber. When first born fiber flow through it, ATO nano particles di
