Abstract：

Polyvinyl alcohol/alginate composite membrane was prepared by using CaCl2 as crosslinking agent. With the swelling degree as the main evaluation index, the influences of polyvinyl alcohol content and crosslinking agent concentration on the water resistance of the composite membrane was analyzed. The micromorphology of the composite membrane was characterized by SEM and AFM. The results indicated that the cross-linking effect of the composite membrane was improved remarkably when the content of polyvinyl alcohol was 60 wt% and the concentration of crosslinking agent was 2wt %, In this condition, the composite membrane had optimum water resistance, hydrophilicity and water retention rate. The SEM and AFM showed that there were good compatibility between polyvinyl alcohol and calcium alginate and improved surface roughness of the composite membrane after crosslinking. This research will provide a certain theoretical basis for the practical application of polyvinyl alcohol/calcium alginate composite membrane.
