| Abstract Scope |
Low temperature plasma processing has been widely used as a non-invasive method for chemical modification of soft-matter and biomatter surfaces. We evaluated the capability of non-equilibrium organic plasma processing (OPP) to generate superhydrophobic, super hydrophilic, and functional surfaces on polymer surfaces for biointerfacing applications. More specifically, methylmethacrylate (MMA) plasma processing was used to generate superhydrophobic surfaces with contact angle of 154 degree. The observed superhydrophobicity can be attributed to physical etching of surface of PTFE by oxygen plasma and the subsequent O2/MMA combined plasma mediated surface chemical film deposition. Similarly, hydrophilic and NO-functional surfaces were prepared using appropriate organic plasma precursors. The OPP treated surface were then systematically investigated using characterizations such as XPS, FTIR, XRD, DSC, OES and SEM analyses. The superhydrophobic/ superhydrophilic and functional surfaces may have the potential to reduce thrombosis or to enhance endothelial cells growth for soft-polymer grafts for their use in small caliber applications. |
