摘要
以三氯化镓(GaCl_3)、氯化锂(LiCl)、苯甲醇、氯化钙(CaCl_2)作为络合剂或溶剂,分别配制PA6/GaCl_3/硝基甲烷(CH_3NO_2)、PA6/LiCl/甲酸、PA6/苯甲醇和PA6/CaCl_2/甲酸等体系,制得冻胶试样,采用差示扫描量热法、红外光谱分析、X射线衍射和扫描电子显微镜等方法对冻胶试样的结构与性能进行了分析对比。结果表明:各个PA6冻胶体系的形成机理不同,各体系冻胶结构和性能差异较大。GaCl_3,LiCl,CaCl_2主要是通过破坏PA6的内部氢键,对其进行络合成冻胶,但三者的络合能力又有所区别。苯甲醇主要是通过溶剂效应而形成冻胶。
Using gallium trichloride （GaCl3 ）, lithium chloride （LiCl）, benzyl alcohol and calcium chloride （CaCl2 ） as complexing agent or solvent, the gel systems of PA6/GaC13/nitromethane （ CH3NO2 ）, PA6/LiCl/formic acid, PA6/benzyl alcohol and PA6/CaCl2/formic acid were prepared. The structure and properties of the gel systems were analyzed and contrasted by differential scanning calorimetry （ DSC）, FT-IR spectroscopy, X-ray diffreaction （ XRD ）, scanning electron microscopy （ SEM ）. The results showed that the different formation mechanism decided the different structure and properties of the gel systems. GaC13 , LiCl and CaCl2 helped the complexation of PA6 into gel systems dominantly by destroying the internal hydrogen bond, but they had different complexation capability. Benzyl alcohol helped the formation of the gel system by solvent effect.
