摘　　要：以丙烯酸镁和丙烯酸钙为单体,乙二醇二丙烯酸酯为交联剂制备了聚丙烯酸盐水凝胶,对其结构、形态和溶胀性能进行了研究.实验表明:聚丙烯酸盐水凝胶具有相互连通的孔洞结构;交联剂的用量是影响水凝胶溶胀速率和溶胀度的一个重要因素,当交联剂用量较低时,水凝胶显示出较快的溶胀速率和较大的溶胀度;聚丙烯酸盐水凝胶具有明显的温度敏感性和pH敏感性.Polyacrylate hydrogel was prepared by using acrylic calcium and acrylic magnesium as monomer,ethane-1,2-diyl diacrylate as crosslinker.The structure,morphology and swelling properties of these hydrogels were studied.It was found that polyacrylate hydrogel had interconnected pore structure,that amount of crosslinker was an important factor,which could influence swelling ratios and swelling rates of polyacrylate hydrogels,when the amount of crosslinker was low,the hydrogels showed a faster swelling ratios and a larger swelling rates;that polyacrylate hydrogel showed obvious temperature and pH-sensitivity.
