Abstract
Methyl methacrylate-grafted phenolic resin fiber was soaked in AgNO3 a queous solution to support Ag+ by ion exchange reaction. The fiber sup porting Ag+ was carbonized at 900-degrees-C for 30 min in a nitrogen a tmosphere, followed by activation at 900-degrees-C under a stream of s team. One of the activated fibers contained 0.58 wt% of silver and sho wed 2100 m2/g of Specific surface area and 200 MPa of tensile strength . This fiber showed antibacterial activity against Staphylococcus aure us and Escherichia coli before and after soaking in the flowing tap wa ter for 20 days. The amount of Ag+ dissolved from the fiber into the w ater is discussed from a viewpoint of practical use.
