纤维素/丝素蛋白共混膜的制备及性能研究

摘要

The composite film was prepared by dissolving cellulose in sodium hydrogen, urea and thio-urea solution then adding the silk fibroin. The compatibility, mechanical property, moisture absorption, moisture retention and moisture permeable property of the composite films were studied. The result showed that cellulose had good compatibility with the silk fibroin when the mass ratio was 4:1.The mechanical property, moisture absorption, moisture retention and moisture permeable property were all relatively high. The comprehensive properties of the cellulose/filk fibroin composite film were better than the pure cellulose film.%选用氢氧化钠-尿素-硫脲体系溶解纤维素,添加丝素蛋白,制得纤维素/丝素蛋白共混膜,研究共混膜的相容性、力学性能及吸湿保湿、透湿性能等.结果表明:m(纤维素)∶m(丝素蛋白)=4∶1时,丝素蛋白与纤维素有良好的相容性,力学性能、吸湿保湿性能、透湿性能等相对较高,纤维素/丝素蛋白共混膜的综合性能优于纯纤维素膜.
