摘要：

Calcium alginate film containing ellagic acid as a functional material was formed on polyethylene nonwoven sheet by the reaction of sodium alginate with calcium chloride in the presence of ellagic acid. The film had the intelligent function of release of ellagic acid triggered by sodium ion. This response resulted from conversion of the water-insoluble calcium alginate to water-soluble sodium alginate. The optimal conditions for the intelligent calcium alginate film prepared on the polyethylene surface were 0.5% CaCl2 solution and 0.05 or 0.1% sodium alginate solution.
