The multiwalled carbon nanotubes(MWNT) were introduced into the polymerization of amino-capped PA6 after oxidization and chloroformylation to produce PA6/MWNT masterbatch which was mixed with PA6 chip and spun into PA6/MWNT fiber via melt blend spinning.

• 将多壁碳纳米管(MWNT)氧化后,酰氯化处理,在氨基封端的PA6聚合时加入,制备PA6/MWNT母粒,将母粒同PA6切片熔融共混纺丝,制备PA6/MWNT纤维。
