doi:10.1002/ppap.201700019engLafuente, M.Martínez, E.Pellejero, I.Artal, M.del CarmenPina, M. del PilarWettability control on microstructured polypropylene surfaces by means of O2 plasmaART-2017-101683Durable and wear resistant polypropylene surfaces with static contact angle (SCA) above 140° have been fabricated using standard photolithographic process and O2 plasma etching followed by thermal annealing at 100 °C. This microfabrication process leads to a hierarchical topography derived from the patterned microstructures and the sub-micron roughness caused by plasma. Hydrophobicity (SCA up to 145°) remained over 14 months after fabrication. This wetting behavior is attributed to the combination of the periodic array of micro-sized pillars with low aspect-ratio and the submicron roughness caused by O2 plasma.2017http://zaguan.unizar.es/record/7723910.1002/ppap.201700019http://zaguan.unizar.es/record/77239oai:zaguan.unizar.es:77239Plasma Processes and Polymers 14, 8 (2017), e1700019 [6 pp]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
