摘　　要：以海藻酸钠为原料,氯化钙水溶液为凝固浴,研究氯化钙质量分数、温度、时间和p H值对海藻酸膜性能的影响。测定了海藻酸膜对蒸馏水、生理盐水和人造血浆(A液)的吸湿性能和力学性能。采用红外光谱(IR)对海藻酸膜进行结构表征。结果表明,在p H值7,氯化钙质量分数2%,凝固浴温度40℃,凝固时间50 s条件下,制备的海藻酸钙膜具有优良的吸湿和力学性能。Alginiate acid membrane is prepared using sodium alginate as raw material and calcium chlo- ride solution as coagulation bath. Effect of calcium chloride concentration, temperature, time and pH val- ue on the performances of alginate acid membrane are studied. The mechanical performance and the absorption properties of membrane for distilled water, normal saline and artificial plasma （A solution） are determined, The structure of alginate acid membrane is characterized by infrared spectroscopy （IR）. The results show that the optimal conditions are pH value 7, calcium chloride 2%, coagulation at 40℃ for 50 s. The calcium alginate membrane possesses excellent moisture absorption and mechanical perfor- mance.
