摘　　要：为找到银离子与载体材料有效结合的方法,分析了目前国际市场上应用的各种银化合物的结构和性能,介绍了目前在国际市场上销售的各种含银医用敷料的制备方法。结果表明:由于金属银的活性很低,在使用金属银时必须保证它的颗粒很细,并且添加在材料的表面;银化合物可以与伤口渗出液中的金属离子发生离子交换,所以在使用时更容易被释放;由于银化合物和载体材料的种类很多,不同的含银医用敷料在性能上有很大的区别。In order to find effective methods to combine silver ions with base material, this paper analyzed the structures and properties of various silver compounds currently available on the international market, and introduced the preparing methods of various silver-contalned wound dressings on the world market. Results showed that since it has a low antimicrobial activity, metallic silver should have very fine particle size and be incorporated into the base material on its surface so that silver compounds can exchange ions with exudates from the wound, making silver ions easy to release. Because of the large varieties of silver compounds and base materials, silver-contained wound dressings differ significantly in their functional properties.
