✦ Synopsis

Hydrophilic surface modification of poly(tetrafluoroethylene) (PTFE) has been carried out by coating with a thin layer of fluoroalkyl‐ terminated poly(ethylene gylcol) (PEG). The coating layer adheres by hydrophobic interactions and is stable, in accord with the sol–gel behavior of the bulk polymer. Stable hydrogel arrays have been prepared by e.g., solvent‐ assisted micromolding on a perfluorosilanized substrate (see Figure).
