Surface Modifications of High Density Polycarbonate by Argon Plasma

─ The polycarbonate (PC) membranes were implanted to 16 W argon ions plasma. The samples were treated for different exposure time 10 min, 30 min and 60 min. The effect of argon ions implantation on optical and chemical properties of PC membrane has been investigated. The observed changes have been correlated with the induced structural changes in the implanted layer using UV-Visible spectroscopy. The Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) were employed to study the surface characteristics of the membrane. The AFM results indicate significant changes in the surface morphology of the polymer membranes before and after plasma treatment. Keywords─ Polycarbonate (PC), Plasma treatment, AFM, SEM, UV-Visible spectroscopy.
