Abstract

This work focused on the development of a new biomaterial from polysaccharides. Thus composite films of sodium alginate, κ-carrageenan, and ι-carra-geenan plasticized with glycerol and poly(ethylene glycol) 400 (PEG 400) were prepared. The surface properties of the resulting films in terms of surface morphology were investigated. The best ratio between glycerol and PEG 400 used as plasticizers to prepare sodium alginate films was determined. Opacity, water content, SEM, TGA, and FTIR studies determined the optimal ratio between glycerol and PEG 400. The addition of carrageenans in the composite films showed differences in the TGA curves and on surface of the films. The composite film was loaded with an ethanolic solution of aminoethoxyvinylglycine (AVG). The AVG loaded in the composite film exhibited improved surface area, increased percent of crystallinity, and higher percent release at a lower temperature and its release kinetics were studied

氨基乙氧基乙烯基甘氨酸负载海藻酸钠/ kappa -卡拉胶/ iota -卡拉胶生物复合膜的制备及Сharacterization

本工作的重点是从多糖中开发一种新的生物材料。为此，制备了海藻酸钠、κ-卡拉胶和ι-卡拉胶经甘油和聚乙二醇400 (PEG 400)塑化的复合膜。从表面形貌的角度研究了所得薄膜的表面特性。确定了甘油与PEG 400作为增塑剂制备海藻酸钠薄膜的最佳配比。不透明度，含水量，SEM, TGA和FTIR研究确定了甘油和peg400之间的最佳比例。卡拉胶在复合膜中的添加量对复合膜的TGA曲线和表面形貌有不同的影响。用氨基乙氧基乙烯基甘氨酸(AVG)乙醇溶液负载复合膜。在低温下，AVG的表面积增大，结晶率提高，释放率提高，并对其释放动力学进行了研究
