摘要/Abstract

摘要： 采用冷冻干燥法，利用海藻酸钠（SA）和魔芋葡甘露聚糖（KGM）共混溶液，制备了一种多糖类复合海绵材料，测定了不同配比中复合海绵材料的孔隙率、吸湿保湿性及力学性能，讨论了甘油的添加量对复合海绵材料柔软性及透气性的影响，并用红外光谱（FTIR）、扫描电镜（SEM）对复合海绵材料的结构进行了表征。研究结果表明，制备的复合海绵材料孔径为100~200μm，气孔为圆形或扁长形，具有良好的连通性和均匀性；SA和KGM通过物理共混的方式共存，并没有发生化学反应。SA和KGM的最佳质量分数比为2.0：0.9，甘油的最佳添加量为4%，此时制备的复合海绵材料具有良好的透气性、吸湿保湿性和较好的力学性能，同时保持了天然多糖优良的生物相容性能，在生物医用材料领域具有潜在的应用价值。

Abstract: A novel polysaccharide sponge was prepared from mixed aqueous solution of sodium alginate(SA)and konjac glucomannan(KGM)using the freeze-drying method. The porosity,moisture absorption and mechanical properties of the composite sponge material with different proportions were determined in this paper. The effects of the addition of glycerol on the softness and permeability of the composite sponge were discussed as well. The structure of composite sponge material was characterized by Fourier transform infrared spectroscopy(FTIR)and scanning electron microscopy (SEM). The result showed that the pore diameters were between 100-200μm,and the pores were with good connectivity and homogeneity and round or elliptical in shape. SA and KGM coexisted by physical blending and no chemical reaction occurred. The optimum ratio of SA and KGM was 2.0:0.9,and the best addition amount of glycerol was 4%. The sponge prepared under such conditions showed excellent biological compatibility of natural polysaccharide. In addition,the porosity,moisture absorption,moisture retention and mechanical properties of sponge are also very good,which renders it great potential in the area of biological materials and medical materials.
