摘要
分别以浓度均为5%的醋酸、硫酸、磷酸、草酸和氯化钙水溶液为凝固体系制备一系列纤维素/大豆分离蛋白共混膜,表征了不同凝固体系对共混膜的结构与力学性能的影响。结果表明,共混膜为多孔网络结构,表面和内部孔径随着大豆分离蛋白含量增加而增加,且以5%醋酸为凝固体系制备的共混膜在干态和湿态下均具有最高的力学强度和最大的表面与内部孔径。由此,5%醋酸溶液是制备具有较好力学强度和较大孔径共混膜最适合的凝固体系。
A series of cellulose/soy protein isolate blend membranes were prepared from cellulose/soy protein isolate solution by coagulating with 5% acetic acid,5% sulfuric acid,5% phosphoric acid,5% oxalic acid,and 5% calcium chloride solution,respectively.The effects of different coagulation system on the structure and mechanical properties of the blend membranes were investigated by various methods.The results revealed that the membranes exhibited porous structure.The pore size in the surfaces and cross-sections o...
