摘要:
丝素与海藻酸钠共混溶液经过碳二亚胺交联后,采用流延法制备的复合薄膜具有良好的相容性,改进了单一膜材的力学性能吸湿性及其稳定性。通过对复合薄膜进行红外光谱和扫描电镜分析不同共混比例复合薄膜的微观结构和聚集态结构;通过拉伸断裂测试、热水溶失率、溶胀率及水蒸气传递速率的测试研究了复合薄膜的基本性能结果表明:经过碳二亚胺交联后,复合薄膜两相相容性提高,无明显的相分离现象,并在丝素和海藻酸钠之间形成了稳定的共价键交联点,薄膜稳定性明显提高,与单一成分薄膜相比,复合薄膜的柔韧性明显增加。海藻酸钠加入有效提高了薄膜的吸湿性能。
Abstract:
After mixtures of silk fibroin solution and sodium alginate solution were crosslinked by carbodiimide, the composite films prepared by flow casting method from the mixtures. The composite films exhibited good compatibility, and improved mechanical properties, hygroscopicity and stability of single film. The microstructure and aggregation structure of the composite films with different blending ratio were analyzed by Fourier Transformed Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM), and its basic properties were characterized by tensile failure test, hot water loss rate, swelling rate and vapor transfer rate. The results showed that the two-phase compatibility of the composite films was improved without obvious phase separation after carbodiimide cross-linking, and the stable covalent bonds between SF and SA formed. The stability of the film was obviously improved, and the tensile strength and elongation of the composite film was obviously enhanced compared with the single component film. The addition of SA effectively improved the swelling property of the film
