## Highly crystallized graphite films were prepared by successive heat treatments at 3100Β°C for 40 minutes and then 3200Β°C for 23 minutes under atmospheric pressure of pure argon gas from thin carbonized polyimide films. The starting polyimide films were a commercially available Kapton and a labor
Graphitizability of various carbonized polyimide films heat treated at 2950Β°C was studied by X-ray and magnetoresistance measurements and SEM observation. The films used were commercially available polyimide films, Kapton and Upilex, and two kinds of laboratory-prepared polyimide films. Results obt
## Abstract This article describes the preparation of porous polyimide composites and carbon foam films with uniform and controllable porous structures, using nickel oleate as a poreβforming agent and as a precursor for catalyst formation for the carbonization process. Pore formation occurs by a ph
