The present invention relates to a method for producing a carbon fiber that can be suitably used as a transparent conductive material for forming transparent flexible conductive films and the like, more particularly, to a method for producing a carbon fiber having an outermost surface composed of edges of graphenes, and to a carbon fiber produced by the production method. The production method comprises a step of pre-baking a fiber of an organic compound so as to contain remaining hydrogen, and a step of putting the pre-baked fiber of the organic compound in a closed vessel made of a heat resistant material and subjecting the pre-baked fiber together with the vessel to hot isostatic pressing treatment using a compressed gas atmosphere, wherein a maximum ultimate temperature in the hot isostatic pressing treatment is 1000 to 2000° C.
本发明涉及一种生产碳纤维的方法,该碳纤维可适当用作透明导电材料,用于形成透明柔性导电薄膜等,更具体地说,涉及一种生产碳纤维的方法,该碳纤维的最外表面由
石墨烯的边缘组成,还涉及用该生产方法生产的碳纤维。该生产方法包括预焙有机化合物纤维使其含有剩余氢的步骤,以及将预焙有机化合物纤维放入由耐热材料制成的密闭容器中,并使用压缩气体环境将预焙纤维和容器一起进行热等静压处理的步骤,其中热等静压处理的最高极限温度为 1000 至 2000°C。
