摘要： A graphite film showing an extremely low average tearing force is more likely to suffer from various kinds of defects, such as splitting, winding deviation, wrinkling, and poor dimensional accuracy, in a step of producing the graphite film and in a step of processing the graphite film. However, these defects can be prevented by using a graphite film that satisfies the following requirements: 1) having an average tearing force of not more than 0.08 N as determined by Trouser tear method in accordance with JIS K7128; and 2) having sag of not less than 5 mm and not greater than 80 mm as determined by a method of film windability evaluation in accordance with JIS C2151.

摘要： When a raw material graphite film bad in flatness is laminated onto another material, creases and other defects may be caused. In particular, when a graphite film having a large area is laminated, defects such as creases may be often caused. In order to solve such defects, a flatness correction treatment step is performed wherein a raw material graphite film is subjected to heat treatment up to 2000° C. or higher while a pressure is applied thereto. This flatness correction treatment gives a graphite film good in flatness. Furthermore, when the flatness of the raw material graphite film is corrected by use of a thermal expansion of a core, a graphite film small in sagging can be obtained.

摘要： Disclosed herein is a method for producing an elongated (rolled) carbonaceous film by polymer pyrolysis while suppressing the fusion bonding of the carbonaceous film. The method for producing a carbonaceous film includes the step of heat-treating a polymer film wound into a roll, wherein the heat treatment is performed after the polymer film is wound into a roll to have a gap between adjacent layers of the polymer film at a temperature lower than a pyrolysis onset temperature of the polymer film so that the roll of polymer film as a whole satisfies a relationship that a value obtained by dividing a thickness of a gap between adjacent layers of the polymer film (Ts) by a thickness of the polymer film (Tf) (Ts/Tf) is 0.16 or higher but 1.50 or lower. As a method for forming gaps between the layers of the polymer film, a method in which the polymer film is wound into a roll together with a slip sheet and then the slip sheet is removed can be used, which is effective at suppressing the fusion bonding of a carbonaceous film.

摘要： The present invention performs special heat treatment on a polymer film in a temperature range from (i) a lower limit to temperature rise being equal to or higher than a starting temperature of thermal decomposition of the polymer film, i.e., which is a temperature observed at an early stage of the thermal decomposition of the polymer film, to (ii) an upper limit to temperature rise being equal to or lower than an intermediate temperature of thermal decomposition of the polymer film. This reduces foaming in the film during graphitization treatment following the special heat treatment. Thus, even with a higher heating rate for graphitization, it is possible to produce a graphite film having good quality.
摘要翻译：本发明在从（i）下限到升温等于或高于聚合物膜的热分解起始温度的温度范围内对聚合物膜进行特殊热处理，即，在聚合物膜的热分解的早期阶段，（ii）升温的上限等于或低于聚合物膜的热分解中间温度。这在特殊热处理之后的石墨化处理期间减少了膜中的起泡。因此，即使用于石墨化的较高加热速率，也可以制造质量好的石墨膜。
