【摘要】：先對(duì)木棉纖維(KF)進(jìn)行親水處理,再用4%(質(zhì)量分?jǐn)?shù))硅烷偶聯(lián)劑KH550在親水KF表面自組裝成膜得到KH550/KF,經(jīng)鎳活化后再進(jìn)行化學(xué)鍍鎳 磷,得到Ni P/KH550/KF輕質(zhì)復(fù)合導(dǎo)電纖維。采用紅外全反射儀(ATR)、X射線衍射儀(XRD)、掃描電鏡(SEM)及能譜儀(EDS)分析了不同處理階段纖維表層的化學(xué)結(jié)構(gòu)、相結(jié)構(gòu)、形貌及組成元素。結(jié)果表明:KH550被成功接枝到親水KF表面。與直接活化法化學(xué)鍍所得Ni P/KF纖維相比,KH550自組裝化學(xué)鍍工藝所得Ni P/KH550/KF復(fù)合纖維表面的Ni P鍍層更致密,電導(dǎo)率為(390.92±10.31)S/cm,有效密度為(3.990 2±0.031 2)g/cm3。
[Abstract]:Kapok fiber was treated by hydrophilic treatment, then KH550/KF was obtained by self-assembly on the surface of hydrophilic KF with 4% silane coupling agent KH550. The electroless Ni-P / KH 550 / KF composite conductive fiber was obtained by electroless plating of nickel and phosphorus after activation of nickel, and the X-ray diffractometer (XRD) was used. Scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS) were used to analyze the chemical structure and phase structure of fiber surface in different treatment stages. The results showed that the KH550 was grafted onto the hydrophilic KF surface, which was compared with the Ni P- P / KF fiber obtained by direct activation electroless plating. The Ni / P coating on the surface of Ni / P / KH _ 550 / KF composite fiber obtained by KH550 self-assembly electroless plating process is denser, and its conductivity is 390.92 鹵10.31g / cm. The effective density is 3.990 2 鹵0.031 2 g / cm 3.
