【摘要】 合成了明胶、聚丙烯酰胺水凝胶以及用碳酸氢钠为致孔剂的超大孔隙聚丙烯酰胺水凝胶。并对其溶胀性、再生性、水解性进行初步测试。通过对这些性质的影响因素的探索得到了一些变化规律。还用扫描电镜观察测量了超大孔隙聚丙烯酰胺水凝胶中孔的型貌和大小。更多还原

【Abstract】 Our study was to synthesize hydrogels from gelatin and polyacrymide (PAM ) (with foam agent or without). We examined their properties of swelling, regeneration and hydrosis. Through the examination of these properties, we found how they were influenced by factors such as solvent, concentration of crosslinking agent. Scanning electron microscope(SEM) was used to characterize the pores size and interior structure of PAM hydro-gel.更多还原
