Abstract

Studies on surface wettability have received tremendous interest due to their potential applications in research and industrial processes. One of the strategies to tune surface wettability is modifying surface topography at micro- and nanoscales. In this research, periodic micro- and nanostructures were patterned on several polymer surfaces by ultra-precision single point diamond turning to investigate the relationships between surface topog- raphies at the micro- and nanoscales and their surface wettability. This research revealed that single-point dia- mond turning could be used to enhance the wettability of a variety of polymers, including polyvinyl chloride (PVC), polyethylene 1000 (PE1000), polypropylene copolymer (PP) and polytetraﬂuoroethylene (PFTE), which cannot be processed by conventional semiconductor-based manufacturing processes. Materials exhibiting com- mon wettability properties (θ ≈ 90°) changed to exhibit “superhydrophobic” behavior (θ 150°). Compared with the size of the structures, the aspect ratio of the void space between micro- and nanostructures has a strong im- pact on surface wettability.
