Abstract

We report a novel plasma surface modification method with surfactant for hydrophobic polymers. Tetrafluoroethylene-perfluoroalkoxyvinyl ether copolymer (PFA) and cyclic olefin copolymers (COC) were employed as hydrophobic polymers. The modified surfaces were characterized by contact angle measurements, adhesion strength measurements and attenuated total reflection infrared (ATR-IR) spectroscopy. The water contact angle of the treated PFA surface decreased significantly from 110 to 66 degrees. Furthermore, no evolution of this surface property occurred over a period of at least 20 days after the treatment. This method allows us to bond directly the modified hydrophobic polymer plates under low temperature. Finally, we demonstrated the micropattening and cell adhesion on the hydrophobic polymers.
