摘要/Abstract

摘要： 纳米炭黑是聚丙烯腈纤维原液着色的关键材料之一，本研究以改性丙烯酸酯嵌段共聚物（SUA020）为分散剂，采用超声波制备了以二甲基甲酰胺（DMF）为分散介质的纳米炭黑，探讨了纳米炭黑对聚丙烯腈纤维原液性能的影响。结果表明当炭黑质量分数为10%，SUA020对炭黑质量分数为20%，在超声波处理功率为600W条件下分散20min，所制备纳米炭黑的粒径为108.7nm。纳米炭黑在聚丙烯腈纤维原液中具有良好的相容性和稳定性，当纳米炭黑对纤维干重为9.0%时，所制备原液着色聚丙烯腈浆膜的K/S值达到最高。

Abstract: Abstract Nanoscale carbon black is one of the important colorant for the dope dyeing of polyacrylonitrile (PAN). In this paper, the nanoscale carbon black which used acrylate block copolymer (SUA020) as dispersant and dimethylformamide (DMF) as dispersing media was prepared by ultrasonic machine, and then the effect of nanoscale carbon black on properties of PAN-DMF spinning solution was further investigated. The results showed that the nanoscale carbon black with particle size 108.7nm was prepared when the mass ratio of carbon black was 10%, SUA020 and carbon black 20%, ultrasonic power 600W and ultrasonic time 20min. The nanoscale carbon black has an excellent miscibility with PAN-DMF spinning solutions. The K/S value of the membrane prepared form PAN-DMF spinning solution and nanoscale carbon black reached to the maximum when amount of nanoscale carbon black was higher than 9%.
