Preparation of silk fibroin-sodium alginate-glycerol blend films and its properties
摘要
Abstract
In this experiment, the blend films were mainly prepared from silk fibroin, and the sodium alginate and glycerol were also added in as additive. Concentration of silk fibroin solution, concentration of sodium alginate solution and glycerin amount were studied which have some effects on the properties of the blend films, including thickness, elongation at break and vapor transfer velocity. The optimal formula for the silk fibroin - sodium alginate-glycerol blend films was determined by orthogonal experiment. The results showed that the best concentration of silk fibroin, concentration of sodium alginate and glycerol amount were 3%, 12.5mg/ml and 0.5 ml, respectively. In this condition, the thickness, elongation at break and vapor transfer velocity of the blend films could reach 0.075 mm, 45.53% and 13.76 g·m-2·h-1, respectively.关键词
