applications for hydrogels, a better understanding of the relation between molecular structure and mechanical properties for well‐defined hydrogel is essential. A new library has been compiled of poly(ethylene glycol) polymers (PEG) of different length end functionalized with diallyl, dithiol, and dimethacrylate, and crosslinked with complementary trifunctional crosslinkers. In this study, the hydrogels were initially
考虑到水凝胶的大量应用,对清楚定义的水凝胶的分子结构与机械性能之间的关系有一个更好的了解是必不可少的。已编译了一个新的库,其中包含用二烯丙基,二硫醇和二甲基丙烯酸酯官能化并用互补的三官能交联剂交联的不同长度末端的聚乙二醇聚合物(PEG)。在这项研究中,最初通过FT-拉曼光谱和NMR分析了水凝胶,以研究官能团的转化率。研究了溶剂类型,固含量,固化时间和PEG链长度对水凝胶最终浸出,溶胀和拉伸性能的影响。©2011 Wiley Periodicals,Inc. J Polym Sci A部分:Polym Chem,2011年
