摘要
用溶液共混法制备海藻酸钠-羧甲基纤维素钠-明胶共混膜,并采用红外光谱(FT-IR)、X射线衍射(XRD)、扫描电镜(SEM)表征膜的结构,同时测定共混膜的透光率、力学性能、水溶性和紫外吸收性。结果表明:共混膜中海藻酸钠、羧甲基纤维素钠、明胶之间存在着强烈的相互作用和良好的相容性,三者共混明显改善海藻酸钠和羧甲基纤维素钠一元膜和海藻酸钠-羧甲基纤维素钠二元膜的性能。
A compound film was successfully prepared by coagulation of sodium alginate （NaAlg）, sodium carboxymethylcellulose （CMC） and gelatin （GLE） in aqueous solution. FT-IR, XRD, SEM and UV-Visible spectroscopy were used for the structural characterization of this compound film, and along with this, its mechanical properties, water solubility and UV absorption were also measured. Results indicated strong interaction and good compatibility among sodium alginate, sodium carboxymethylcellulose and gelatin were observed. This compound film showed obviously improved physical and chemical properties, when compared with single NaAlg and CMC films and their compound film.
