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.

Abstract: The present invention relates to: a method for plating nonwoven fabric with metals (copper and nickel, or nickel and nickel) by electroless and electrolytic continuous processes; and a nonwoven fabric plated by the method. The present invention can prepare a metal-plated nonwoven fabric by electrolytic plating a space of metal ions, which are formed by performing electroless plating with copper or nickel, with nickel in a short amount of time, thereby filling up the space, and thus has excellent conductivity while being thin. A desired conductivity can be obtained by changing the composition of a plating solution or controlling the plating velocity, and a line capable of performing plating with copper and nickel, nickel and nickel, nickel alone, or copper alone, in combination, can be manufactured. In addition, a highly conductive nonwoven fabric having no difference in plating thickness of nonwoven fabric performed by only electroless plating can be produced.
