Fabrication of stable and functional patterns on the surface of PTFE remains a great technical challenge owing to its inertness and high hydrophobicity. Here, we report for the first time the fabrication of functional micropatterns on the PTFE surface by selectively irradiating plasma-treated PTFE coated with the monomer solution. A series of uniform highly dense poly(dopamine methacrylamide) (denoted as PDMA) line patterns with line/pitch widths of 20/20 and 50/50 µm are fabricated on the surface of PTFE (denoted as PDMA-p/PTFE) using dopamine methacrylamide (DMA) as the monomer. Surface graft copolymerization occurs and is attributed to the universal adsorption of DMA and the low grafting energy barrier, compared with the polymerization energy barrier, which is also demonstrated by the DFT calculations. Further, robust well-defined metal Ag or Cu patterns with strong adhesion strength are fabricated on the surface of the PTFE film by electroless deposition and are demonstrated for applications in flexible electronics. The approach is demonstrated to be versatile for fabrication of PDMA micropatterns onto a wide range of polymeric substrates, including polypropylene and acrylonitrile butadiene styrene.
