Preparation of film materials made of biological polysaccharidesand their composite formation with apatite

以糖胺聚糖和壳聚糖为原料，采用热压法制备了生物多糖水不溶膜。明确了各多糖组合的最佳条件。考察了多糖的结构和分子量对膜物理性能的影响。在体液条件下，羟基磷灰石沉积在这些膜上。为了快速获得更大尺寸的薄膜，还研究了薄膜制备工艺的改进。

The preparation process to obtain water-insoluble films of biological polysaccharides was established by hot pressing of polyion complexes made of glycosaminoglycans and chitosan. The optimal condition for each polysaccharide combination was clarified. Effects of structure and molecular weight of polysaccharides on physical properties of the resulting films were evaluated. Hydroxyapatite deposition on these films under body fluid conditions was achieved. To obtain larger sizes of the films rapidly, improvement of the film preparation process was also examined.
