羽毛角蛋白/海藻酸钠共混膜的交联改性
Crosslinking modification of feather keratin/sodium alginate blend films
摘要
Abstract
Crosslinked and sorbitol-plasticized feather keratin (FK)/sodium alginate (SA)blend films were prepared by the casting process,using glyoxal,glutaraldehyde,or alginate dialdehyde (ADA)as crosslinker. The effects of crosslinking modification on the structure and properties of the blend films were investigated. FTIR analysis confirmed the crosslinking reaction in the process of modification. SEM results showed that crosslinking made the microstructure of the blend films more compact. After crosslinking,the thermal stability and moisture resistance of the blend films were enhanced,the transmittance and the elongation at break decreased. The tensile strength increased when crosslinked with glyoxal or glutaraldehyde,and decreased when crosslinked with ADA.关键词
