Abstract: The present invention relates to a nonwoven fabric or nonwoven composite material comprising the nonwoven fabric for shielding and absorbing electromagnetic waves, manufactured by using a carbon fiber plated with metal (copper and nickel) produced in an electroless or electrolysis continuous process. The nonwoven fabric of the present invention is thinner and stronger than the conventional art, and has an advantage of being capable of controlling conductivity by controlling only the content of the carbon fiber plated with metal, without need for further addition of conductive powder.

Abstract: The present invention relates to a preparation method for an electromagnetic wave shield composite material and the electromagnetic wave shield composite material prepared by the method. The present invention uses a highly conductive carbon fiber prepared by electroless and electrolytic continuous processes, and thus is suitable for an EMI shield due to having an excellent conductivity and low surface resistance, and is capable of providing the electromagnetic wave shield composite material having an excellent productivity and economic value. Furthermore, the electromagnetic wave shield composite material of the present invention can be used for blocking electromagnetic waves by being inserted into a cell phone cover and a cell phone pouch, and can also be applied to a bracket for protecting an LCD of a portable display product.
