Zusammenfassung:The present invention relates to a method for manufacturing an electroconductive carbon paper. According to the present invention, when a plastic material such as polyimide film having excellent heat resistance, electrical insulation, and chemical resistance properties is plasticized by a specific process at ultra-high temperature of 2,000°C or more, the properties of the plastic material are changed into a carbon paper which is a carbon compound having ultra-thermal conductivity properties different from that of the plastic material. The carbon paper has very excellent thermal conductivity and exhibits electrical conductivity, but has the thermal conductivity remarkably degraded as compared to that of copper (Cu) or aluminum (Al). In an advanced electronic product, a function of emitting heat to a desired place in a short time and a power supply or grounding function are sometimes required at the same time. Herein, electrical conductivity is required with high thermal conductivity at the same time. The conventional invention solves a problem in response to an above request by physically or chemically bonding a conductive material such as a copper or aluminum thin plate to the carbon paper. However, the method of the present invention is to increase electrical conductivity by adding a process of injecting an electroconductive additive (dopant), vacuum-depositing or plating a metal having high electrical conductivity, and implanting an electroconductive induced ion in a process of manufacturing the carbon paper, and applying the same to unique properties of the carbon paper. 내열성, 전기절연성, 내화학성, 등이 뛰어난 폴리이미드 필름(Polyimide film) 등의 플라스틱소재를 2000℃ 이상의 초고온으로 특정 공정을 통해 소성(燒成), 가공할 경우 원래 그 소재가 가진 특성과는 상이한 초열전도 특성을 가진 카본(Carbon)화합물인 '카본페이퍼(Carbon-Paper)'로 그 물질의 특성이 변하게 된다. 이러한 '카본페이퍼'는 열 전도성이 아주 우수하며 전기 전도성도 띄지만 구리(Cu)나 알루미늄(Al) 등에 비해서는 전기전도성이 현격히 떨어진다. 첨단 전자제품의 경우, 때에 따라서는 빠른 시간 안에 열을 원하는 곳으로 뽑아내면서 동시에 전원 또는 접지의 기능이 요구되는 경우가 있으며 이러한 경우에는 높은 열전도성과 함께 전기전도성이 동시에 요구되게 된다. 기존에는 이러한 요구에 대하여 '카본페이퍼'에 구리나 알루미늄 박판(薄板) 등의 전도성 물질을 물리적 또는 화학적 방법으로 합착함으로써 그 문제를 해결하였다. 그러나 본 발명은 '카본페이퍼' 제작공정에서 전기전도성 첨가물(Dopant)의 주입, 전기전도성이 높은 금속의 진공증착 또는 도금, 전기전도성 유도이온주입 등의 공정을 추가함으로써 '카본페이퍼'의 고유특성에 부가하여 전기전도성을 높이는데 그 목적이 있다.
