摘要
以壳聚糖和丝素 2种高分子物质溶液按最适比例混合 ,再加入戊二醛后 ,在聚乙烯薄膜上均匀涂布 ,真空干燥成合金膜 ,并对合金膜的外观、溶胀度、酶固定化效果等性状做了研究 .结果表明 ,壳聚糖 丝素合金膜的柔韧性好 ,在不同pH值下的溶胀度稳定 ,具有亲水性强 ,含游离氨基多等优点 。
s: Mixed with chitosan and fibroin solution in suitable volume proportion and dried together with glutaraldehyde, the blend membranes was prepared.The thickness of the membrane was 1.3 μm. Because of the good characters of pliable and tough,stability of swelling ratio and comprising abundant amino groups, the blend membranes were good carrier for immobilizing enzyme, especially those with negative charge.
