ポリイミドヘのパルス•レーザ照射によつて得られる炭素フィルムとその応用

抄録

Carbon film has been prepared by irradiation of pulse YAG laser (wave length 1064nm) to polyimide film under N₂ or ordinary atmosphere. By laser irradiation polyimide were transferred to carbon film, with low degree of crystallinity, The room temperature electrical resistivities are about 0.1Ω•Cm, and their temperature dependencies are similar to those of amorphous or turbostratic carbons with negative temperature coefficient. Carbon as well as electroplated circuit by Ni was successfully prepared in finer pattern than those formed by conventional printing method of conducting paint.
