    • Disclosed herein is a method for producing a roll-shaped carbonaceous film by polymer pyrolysis while suppressing the occurrence of fusion bonding in the roll-shaped carbonaceous film. The carbonaceous film production method includes the step of heat-treating a polymer film wound into a roll, wherein, at a temperature equal to or higher than the pyrolysis onset temperature of the polymer film but equal to or lower than a temperature at which the weight of the polymer film is reduced by 40% as compared to that before heat treatment, the roll-shaped polymer film has (2-1) a gap between layers of the polymer film so that a value determined for the whole roll-shaped polymer film by dividing the thickness of the gap between adjacent layers of the polymer film (Ts) by the thickness of the polymer film (Tf) (Ts/Tf) satisfies a relationship of 0.33≦Ts/Tf≦1.50 and/or (2-2) a space inside a 50% cross-sectional circle of the roll-shaped polymer film so that the area of the space inside the 50% cross-sectional circle is 25% or more of the cross-sectional area of the 50% cross-sectional circle.
    • 本文公开了一种通过聚合物热解制备辊状碳质膜的方法,同时抑制辊状碳质膜中的熔融粘合的发生。 含碳膜的制造方法包括对卷绕成卷的聚合物膜进行热处理的步骤,其中,在等于或高于聚合物膜的热解开始温度的温度下,但等于或低于重量 的聚合物膜与热处理相比降低了40%,所以辊状聚合物膜具有(2-1)聚合物膜的层间的间隙,使得对于整个辊状聚合物膜确定的值 通过将聚合物膜(Ts)的相邻层之间的间隙的厚度除以聚合物膜的厚度(Tf)(Ts / Tf)之间的间隔的厚度满足0.33≤n1E; Ts / Tf< lE; 1.50和/或(2- 2)辊状聚合物膜的50%横截面圆内的空间,使得50%横截面圆内的空间面积为50%横截面的横截面积的25%以上 截面圆。
