Facile hydrophlic surface modification of poly(tetrafluoroethylene) (PTFE) was investigated. Polyethylene glycol (PEG) were telechelically modified with fluoroalkyl hydrophobic groups and thin hydrogel layer was transferred onto PTFE surfaces by dip-coating. It was observed that the physisorption of PEG onto PTFE changes the surface properties of PTFE from hydrophobic to hydrophilic.
