A Simple and Effective Method to Adjust the Structure and Performance of DLC Films on Polymethyl Methacrylate(PMMA) Substrate

DLC (diamond-like carbon) films were prepared on Ti/PMMA(polymethyl methacrylate) under the different bias; principal purpose of this study is to explore structural differences Ti/PMMA with and without conductive material, further clarify role Ti interlayer in influencing deposition mechanism. The results indicate that deposited material exhibit uniform structure mechanical hardness when bias voltage ≥550 V. Furthermore, does not change wettability PMMA, while addition virtually increases risk peeling off film. tribological demonstrate have better properties than those adhesive. This research work can provide basic theoretical guidance for depositing PMMA even all non-conductive substrates.
