It is attempted to produce carbon films having high strength and toughness from thin polymer film by heat treatment. Poly (α-chloroacrylonitrile) was chosen as starting material and pyrolized at various temperatures up to 1200°C. In order to investigate the characteristics of such carbonized films, mechanical properties, electrical conductivity and infared absorption spectra were measured. The film obtained by 1300°C showed relatively high tensile strength of about 370 MPa which was seven times as large as the strength of the untreated polymer. It is concluded that poly (α-chloroacrylonitrile) is a successful raw material for making high preformance carbon films.
