Abstract

Fluorination of polymer surfaces has technological applications in various fields such as microelectronics, biomaterials, textile, packing, etc. In this study PMMA surfaces were fluorinated using DC glow discharge plasma. Tetrafluoroethane was used as the fluorinating agent. On the fluorinated PMMA surface, static water contact angle,surface energy, optical transmittance (UV–vis), XPS and AFM analyses were carried out. After the fluorination PMMA surface becomes hydrophobic with water contact angle of $107^o$ without losing optical transparency. Surface energy of fluorine plasma-treated PMMA decreased from 35 $mJ/cm^2$ to 21.2 $mJ/cm^2$. RMS roughness of the fluorinated surface was 4.01 nm and XPS studies revealed the formation of C–$CF_x$ and $CF_3$ groups on the PMMA surface.
