Universidad de Zaragoza Creation of superhydrophobic and superhydrophilic surfaces on ABS employing a nanosecond laser 2018 Access copy available to the general public Unrestricted A nanosecond green laser was employed to obtain both superhydrophobic and superhydrophilic surfaces on a white commercial acrylonitrile-butadiene-styrene copolymer (ABS). These wetting behaviors were directly related to a laser-induced superficial modification. A predefined pattern was not produced by the laser, rather, the entire surface was covered with laser pulses at 1200 DPI by placing the sample at different positions along the focal axis. The changes were related to the laser fluence used in each case. The highest fluence, on the focal position, induced a drastic heating of the material surface, and this enabled the melted material to flow, thus leading to an almost flat superhydrophilic surface. By contrast, the use of a lower fluence by placing the sample 0.8 µm out of the focal position led to a poor material flow and a fast cooling that froze in a rugged superhydrophobic surface. Contact angles higher than 150° and roll angles of less than 10° were obtained. These wetting behaviors were stable over time. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.972 2018 MATERIALS SCIENCE, MULTIDISCIPLINARY 102 / 293 = 0.348 2018 Q2 T2 0.686 2018 Materials Science (miscellaneous) 2018 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-0922-5615 Oriol, L.
