A hard carbon film can be converted from poly(phenylcarbyne) polymer precursor by a simple and economic process in the temperature range 800-1200 o C at 1atm pressure of an inert gas. The polymer is easily soluble in organic solvents, which can be coated on a complex shape with large area. Under heat-treatment at high temperature (above 800 o C) for 2h, the polymer film on graphite...
Tetrahedral amorphous carbon (ta-C) films were deposited by the filtered cathodic vacuum arc technique with substrate temperature ranging from 25 to 400 o C. A transition from diamond-like properties to graphitic properties was observed for deposition above a threshold temperature value, which is found to increase from 200 to 300 o C for films deposited at different ion energies of...
