METHOD TO MANUFACTURE CARBON PAPER/EPOXY ELECTROMAGNETIC SHIELDING MATERIAL USING ELECTROLESS NICKEL PLATING

摘要

The present invention relates to a method to manufacture a carbon paper/epoxy electromagnetic shielding material, which comprises: (a) a step of immersing pitch-based carbon fiber in a metal plating solution to plate the carbon fiber; (b) a step of mixing an organic polymer compound with the plated carbon fiber via a wet method to make a carbon fiber web; (c) a step of immersing the made carbon fiber web in a thermosetting resin; and (d) a step of hardening the immersed carbon fiber web. According to the present invention, nickel induces reflection and absorption of electromagnetic energy on the pitch-based carbon fiber formed through electroless plating to provide an excellent electromagnetic shield ratio, thereby providing effects of realizing high economic efficiency, a lightweight shape, and a small thickness compared to an existing epoxy composite material, while being applicable to various fields, such as an electronic device, a communication device, a precise device, a smart industry, and the like.;COPYRIGHT KIPO 2019
