A method can be used to provide electrically-conductive articles with electrolessly plated metal, or articles having antimicrobial properties for marine environments. The method includes disposing a silver-containing composition onto one or more supporting sides of a substrate such as continuous polymeric web. The silver-containing composition comprises a water-soluble complex of a reactive polymer with reducible silver ions, the reactive polymer comprising: (a) greater than 1 mol % of recurring units comprising sulfonic acid or sulfonate groups, (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition, and optionally (c) at least 1 mol % of recurring units comprising a pendant amide, hydroxyl, lactam, phosphonic acid, or carboxylic acid group. The reducible silver ions can be suitably reduced and the reactive polymer can be photoexposed to provide crosslinking in patternwise or uniform fashion.
该方法可用于为具有电导性的物品提供电化学镀金属,或为海洋环境具有抗菌性能的物品。该方法包括将含银组成的配方置于基材的一个或多个支撑面上,例如连续聚合物网。含银组成的配方包括与可还原银离子反应的聚合物的水溶性复合物,该反应性聚合物包括:(a)重复单元中含有磺酸或磺酸盐基团的摩尔数大于1%,(b)重复单元中至少有5%含有通过[2+2]光氧加成能够交联的挂链基团,以及可选地(c)重复单元中至少有1%含有挂链酰胺,羟基,内酰胺,膦酸或羧酸基团。可将可还原银离子适当还原,并可对反应性聚合物进行光曝光,以实现图案化或均匀交联。
