| 摘 要： | 利用原位自由基聚合方法合成了聚丙烯酰胺/纳米SiO2复合凝胶,并用红外光谱测定了凝胶化过程中几个典型的反应阶段的红外光谱图,结果表明,复合材料在凝胶化过程中,不仅存在聚合交联反应,同时内部还可能有氢键的形成或其他一些化学作用.用光学显微镜观察了不同纳米粒子含量的复合凝胶的表面形貌,研究表明,纳米粒子在凝胶中并没有出现团聚,表面仍为均匀体系.

| Abstract: | Polymeric hydrogels composed of polyacrylamide and silica particle were prepared by in-situ free-radical polymerization of acrylamide in the presence of silica nanoparticles.The FTIR spectra show that there were some crosslinking reactions as well as the formation of hydrogen bonds or other chemical reactions during gelation.In addition,the high transparency of this hydrogel implies the homogeneity and well dispersion of the inorganic nanoparticles. |
