Carbon film has been prepared by pulse-YAG laser (lambda=1064nm, pulse width ; 8ns) irradiation to the Kapton-type polyimide film under N_2 and air atmosphere, and the structure has been characterized by optical microscope, SEM,TEM,EPMA and Raman spectroscopy by comparing with those obtained through ordinary heat treatment under Ar atmosphere using graphite resistance furnace. The structure of the film, electrical propeerties and electorplating as one of the promissing applications have been studied. The main results of the present project are as following,1) Carbon film has been prepared by irradiation of pulse YAG laser (wave length 1064nm) to polyimide film under N_2 or ordinary atmosphere. By laser irradiation polyimide were transferred to carbon film, with low degree of crystallinity. The room temperature electrical resistivities are about 0.1*・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.2) Carbon films are obtained successfylly by choosing the preparation contditions of the pulse laser irradiation to Kapton film. in the atmosphere of N_2 and even in air. They have a characteristic pebble-like texture, as observed by optical mmicroscope, caused by rapid carbonization. The carbon films obtained have been evaluated to be the same crystallographic structural level as 2000ﾟC heat-treated Kapton film by Raman profile analysis.Present results could contribute for establishment of new approach of carbonization in order to get new forms of carbons with functional properties as well as new practical applications of carbon films prepared directly from polymer by rapid carbonization.

在N_2和空气气氛下，用脉冲YAG激光（λ =1064nm，脉宽8ns）辐照聚酰亚胺薄膜制备了碳膜，并用光学显微镜、SEM、TEM、EPMA和拉曼光谱对碳膜的结构进行了表征，并与用石墨电阻炉在Ar气氛下常规热处理的碳膜进行了比较。研究了薄膜的结构、电性能以及作为一种有希望的应用之一的电镀。本课题的主要研究结果如下：1）在N_2和常压下，用脉冲YAG激光（波长1064nm）照射聚酰亚胺薄膜，制备了碳膜。用激光辐照聚酰亚胺薄膜时，聚酰亚胺薄膜的结晶度较低，转化为碳膜。其室温电阻率约为0.1 ×·cm，其温度依赖性类似于具有负温度系数的无定形碳或乱层碳。2）通过选择脉冲激光辐照Kapton薄膜的制备条件，成功地制备出了碳薄膜，并成功地制备出了比传统的印刷导电涂料更精细的碳薄膜和镍电镀电路。在N_2气氛中甚至在空气中。用光学显微镜观察，它们具有典型的卵石状结构，这是由于快速碳化造成的。通过拉曼光谱分析，证明所制备的碳膜与2000 ℃热处理的Kapton膜具有相同的晶体结构水平，这一结果有助于建立新的碳化方法，以获得具有功能性的新型碳，并为聚合物直接碳化制备碳膜提供新的实际应用。
