摘要
以共混法制备了鸡毛角蛋白/淀粉复合膜,并对复合膜的力学性能进行了测试。研究表明:增塑剂(丙三醇)和淀粉的质量比可改变复合膜的力学性能。鸡毛角蛋白的加入可增加淀粉膜的抗张强度和断裂伸长率,当鸡毛角蛋白/淀粉的质量比为0.15时,复合膜的力学性能良好,吸水百分率小,抗水性较好,可适用于碱性物质的包装。不同pH条件下,鸡毛角蛋白/淀粉复合膜对罗丹明B具有不同的控制释放性能,因此有望作为一种新型的pH敏感的药物载体材料。
Chicken feather keratin/starch composite film was prepared by blending method, and its mechanical properties were investigated. The mechanical properties of composite film was changed by the mass ratio of glycerol/ starch. Addition of chicken feather keratin can increase the starch film tensile strength and elongation at break. When the chicken feather keratin/starch composite film mass ratio gets to 0. 15, it shows good mechanical performance, small water absorption percentage, and better water resistance, so it can be used in the packaging of alkaline sub stances. The control release performance of chicken feather keratin/starch composite membrane for Rhodamine B has difference when it in different pH conditions. Herein, it is expected as a new type of pH sensitive drug carrier material.
