Abstract
A novel polygonal barrel-plasma enhanced chemical vapor deposition (PB-PECVD) method was developed to prepare powdered materials with diamond-like carbon (DLC) films. To investigate the effects of frequency on the DLC film preparation, frequency power supplies of 250kHz and 13.56MHz were used and a DLC film was successfully formed on an SiO2 glass plate at 250kHz. The PB-PECVD process was further examined by using polymethyl methacrylate (PMMA) powder sample. It was determined that a DLC film could be uniformly deposited onto the PMMA particles by rotating a hexagonal barrel including the PMMA sample during the PB-PECVD procedure while operating at 250kHz.
