利用溶液共混法制备了胶原蛋白-葡甘聚糖(C-KGM)其混膜。通过FT-IR、X-RD、扫描电镜对共混膜进 行了结构表征,同时测定了共混膜的透光率、力学性能、吸水率、透水汽性和热稳定性。结果表明:葡甘聚糖、胶原蛋白之间存在着强烈的相互作用和良好的相容性,(C-KGM)膜的力学性能和热稳定性明显优于2种单 一聚合物,作为一种潜在的可食性包装膜将具有良好的应用前景。 Collagen-glucomannan (C-KGM) was prepared by solution blending method. The blends were characterized by means of FT-IR, X-RD and scanning electron microscopy. The light transmittance, mechanical properties, water absorption, water vapor permeability and thermal stability of the blends were measured. The results showed that there was a strong interaction and good compatibility between glucomannan and collagen. The mechanical properties and thermal stability of (C-KGM) film were better than those of two single polymers, Potential edible packaging film will have a good prospect.
