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： Disclosed herein is a production method capable of efficiently producing a carbonized film wound into a roll without the occurrence of fusion bonding between the layers of the film. The method includes a carbonization step in which a polymer film wound around a core is placed in a heating furnace and carbonized by heat treatment to obtain a carbonized film wound around the core. The carbonization step is performed by increasing a temperature of the heat treatment from an initial temperature through a pyrolysis onset temperature to a pyrolysis end temperature. In the carbonization step, the heating furnace is decompressed when the temperature of the heat treatment is lower than the pyrolysis onset temperature, and after the temperature of the heat treatment reaches the pyrolysis onset temperature, the heating furnace is not decompressed or the heating furnace is decompressed so that an absolute pressure in the heating furnace is in a range of 21.3 kPa to 101.29 kPa.

摘要： Disclosed herein is a method for producing an elongated (rolled) carbonaceous film by polymer pyrolysis while suppressing the fusion bonding and the rippling 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 at a temperature lower than a pyrolysis onset temperature of the polymer film so that the roll of polymer film has a center and has a space inside its cross-sectional circle (50% cross-sectional circle) (space within 50% cross-sectional circle) whose center is at the center and whose circumference passes through a point at which a length of the polymer film from an inner end thereof is 50% of a total length of the polymer film and that an area of the space within 50% cross-sectional circle is 25% or more of an area of the 50% cross-sectional circle. Particularly, providing a space between a core and an innermost layer of the roll of polymer film is more effective at solving the above problem.
