Preparation of Polymer Metal Composite Film as a Precursor of Metal Doped Carbon Membrane via Supercritical Impregnation

摘要

Preparation of noble metal (Pt, Pd) particle-dispersed polyimide film as a precursor of metal doped carbon molecular sieve membrane was performed using impregnation of acetylacetonato complex dissolved in supercritical CO_2. Pt and Pd nanoparticles were successfully formed inside of the polyimide films, The impregnation temperature and varieties of polyimide films were strongly affects the dispersion of the metal particles.
