Heating Characteristics of Films Prepared with Polymer-Graphite Composites
Sheet resistance and heating temperature as a function of the amount of graphite added to the heating film. Open symbols (○ and □) and filled symbols (● and ■) represent the sheet resistance and the temperature measured in the film, respectively. The abbreviations in the figure represent as follows: PBGr: polybutadiene/graphite composite film; PMMAGr: poly(methyl methacrylate)/graphite composite film. () and () after the abbreviations mean the sheet resistance and the temperature, respectively. Infrared thermal images were taken from the heating films while applying DC power of 24 V; (a) PMMAGr and (b) PBGr films including 50 wt.% of graphite. Thickness of both films was about 100 μm.
