摘要
应用 X-射线粉晶衍射 (XRD)、红外吸收光谱 (IR)的方法 ,对高岭土 -淀粉接枝共聚丙烯酰胺超吸水性复合材料进行表征 .结果表明 ,在超吸水性复合材料的制备中 ,高岭土粉体的结构依然保存 ,分散度提高 .同时 ,高岭土粉体表面的羟基、淀粉上的羟基与丙烯酰胺单体等 ,发生了接枝共聚反应 .
By applying the methods of X ray powder diffraction and infrared spectrum, the characterization is carried out on the composite material of clay starch acrylamide graft copolymer with super hygroscopy. Inpreparing composite material with super hygroscopy, structure of kaolinite powder is shown by the result to be unchanged while the diversity is enhanced; and moreover, graft copolymerization occurs on the hydroxy groups over the surface of kaolinite powder, and on the hydroxyl groups over starch and on the monomers of acrylamide.
