摘要

探讨了碳纤维(CF)表面镍金属的化学镀工艺

制备了镀镍碳纤维(NiCF)

采用密炼工艺制备了ABS基体复合材料

研究了CF和NiCF含量对复合材料的导电性能及电磁屏蔽效能的影响。结果表明:采用化学镀的方法在碳纤维表面镀覆了金属镍

所形成的镀层均匀致密;镀覆时间为5min时

镀镍后的碳纤维电阻率降低两个数量级;复合材料电阻率随CF、NiCF含量的增加而逐渐减小;复合材料电磁屏蔽效能随CF、NiCF含量的增加而逐渐增加

当NiCF含量为25%(wt)(约13.3vol%)时

电磁屏蔽效能最高可达51dB。

Abstract

This research investigated the metal-coating method of carbon fibers (CF). Nickel-coated carbon fibers (NiCF) were fabricated by electroless plating

and ABS composites filled with CF and NiCF were prepared by kneading method. The influence of CF and NiCF contents on the electrical conductivity and electromagnetic shielding effectiveness of ABS based composites was studied. The results indicated that an even and intact nickel coating could be plated on carbon fibers under a suiltable pretreatment and plating conditions

and the electrical resistivity of CF decreased 2 orders of magnitude when the plating time was 5min. The electrical resistivity of composites decreased with CF and NiCF content increasing. The corresponding electromagnetic shielding effectiveness of composites increased as filler content increasing

and the value reached 51 dB for the composite containing 25wt% (13.3vol%) NiCF.
