采用生物高分子壳聚糖修饰可溶性蛋壳膜蛋白（SEP）薄膜的力学性能。采用10%醋酸溶液浇铸法制备SEP/壳聚糖共混膜。随着壳聚糖用量的增加，共混膜的抗拉强度和断裂伸长率均有所提高。用场发射扫描电镜观察了微相分离，用红外光谱分析了两组分之间的相互作用。NIH3T3细胞培养结果表明，含10% ~ 50%壳聚糖的SEP/壳聚糖共混膜的生物相容性明显优于纯壳聚糖。
Biopolymer chitosan was used to modify the mechanical properties of soluble eggshell membrane protein (SEP) films. The SEP/chitosan blend films were prepared by solution casting from 10% aqueous acetic acid. Tensile strength and elongation at break of the blend films increased with increasing amount of chitosan. Microphase separation was observed by field emission scanning electron microscopy, although interaction between the two components was revealed by FTIR. The biocompatibility of SEP/chitosan blend films containing 10%-50% of chitosan, as demonstrated by cell culture of NIH3T3, was much better than that of pure chitosan.
