摘要
先对木棉纤维(KF)进行亲水处理,再用4%(质量分数)硅烷偶联剂KH550在亲水KF表面自组装成膜得到KH550/KF,经镍活化后再进行化学镀镍–磷,得到Ni–P/KH550/KF轻质复合导电纤维。采用红外全反射仪(ATR)、X射线衍射仪(XRD)、扫描电镜(SEM)及能谱仪(EDS)分析了不同处理阶段纤维表层的化学结构、相结构、形貌及组成元素。结果表明:KH550被成功接枝到亲水KF表面。与直接活化法化学镀所得Ni–P/KF纤维相比,KH550自组装化学镀工艺所得Ni–P/KH550/KF复合纤维表面的Ni–P镀层更致密,电导率为(390.92±10.31)S/cm,有效密度为(3.990 2±0.031 2)g/cm3。
Hydrophilic treatment was firstly carried out on kapok fiber （KF）, and a self-assembled monolayer was then formed on the hydrophilic KF by treating with 4wt% silane coupling agent KH550 （marked as KH550/KF）. A light- weighted and conductive Ni-P/KH550/KF composite fiber was finally obtained through nickel activation followed by electroless Ni-P plating. The chemical structure, phase structure, micromorphology and elemental composition of the fiber at different treatment steps were analyzed using attenuated total reflectance （ATR） infrared spectrometer, scanning electron microscope （SEM）, X-ray diffractometer （XRD） and electronic dispersive spectrometer （EDS）. The results indicated that KH550 was successfully grafted onto hydrophilic KF surface. The Ni-P/KH550/KF composite fiber prepared via KH550 self-assembly followed by electroless plating has a conductivity of 390.92~10.31 S/cm and an effective density of 3.9902 ＋0.0312 g/cm3, and is more compact as compared with the Ni-P/KF fiber prepared by electroless plating after direct activation.
