Title:
MULTI-METAL COMPOUNDING METHOD FOR POLYMERIC FIBER MATERIAL, AND MULTI-METAL COMPOSITE FIBER
Document Type and Number:
WIPO Patent Application WO/2023/202267
Kind Code:
A1
Abstract:
The present application discloses a multi-metal compounding method for a polymeric fiber material and a multi-metal composite fiber. The method comprises: etching a polymeric fiber in an etching solution containing an oxidizing acid and a hydrophilic agent to obtain a micro-etched fiber; performing surface activation treatment on the micro-etched fiber to obtain an activated fiber; and depositing a multi-metal composite layer on the surface of the activated fiber, the multi-metal composite layer at least comprising an electroless nickel plated bottom layer applied on the surface of the activated fiber and at least one electroplated copper layer. According to the multi-metal compounding method for a polymeric fiber material provided by the present application, the oxidizing acid and the hydrophilic agent are used in combination, so that the phenomena of cracking, ineffective etching, and fiber agglomeration of the polymeric fiber are avoided, and the bonding force, uniformity, and mechanical property of the multi-metal composite layer and the polymeric fiber are improved.
