Method for fabricating electrically conductive carbon paper

When a plastic material that is excellent in terms of heat resistance, electric insulating property, chemical resistance, and the like, such as polyimide film, is sintered/processed through a specific process at a super-high temperature of 2000oC or higher, the material changes characteristics and becomes "carbon paper", which is a carbon compound having super-thermal conductivity different from the original characteristics of the material. The carbon paper has a very excellent thermal conductivity and exhibits a degree of electric conductivity, but the electric conductivity is substantially lower than that of copper (Cu), aluminum (Al), or the like. A cutting-edge electronic product is, in some cases, required to have a power supplying or grounding function while being able to draw heat to a desired location within a short period of time. Such a case requires both high thermal conductivity and high electric conductivity. Such a request has conventionally been satisfied by bonding "carbon paper" and a conductive material, such as a copper or aluminum thin plate, by a physical or chemical method. However, the purpose of the present invention is to improve the electric conductivity of "carbon paper", in addition to its unique characteristics, by adding a process of injecting an electrically conductive dopant, a process of vacuum-depositing a highly electrically conductive metal, a plating process, a process of injecting electrically conductive inductive ions, or the like to the "carbon paper" fabricating process.
