具有电磁屏蔽功能的碳纳米管复合Lyocell纤维
Carbon Nanotube Composited Lyocell Fiber for Electromagnetic Shielding
摘要
Abstract
Carboxymethyl cellulose sodium(CMC)was used as a dispersant to realize the dispersion of multi-walled carbon nanotubes(MWCNTs)in N-methylmorpholine-N-oxide(NMMO)solution.The mixed solution was concentrated,then wood pulp powder was added.Lyocell fibers with different MWCNTs contents were prepared by the dry-jet wet spinning method.Among them,the tensile strength of 10%-MWCNTs@Lyocell reached 3.82 cN/dtex,the elongation at break was 12.71%,and the resistivity could reach 4.8×105 Ω·cm.This fiber was woven into fabric,achieving an electromagnetic shielding efficiency of 13 dB in the X-band,making it good electromagnetic shielding material.关键词
