Issue Date: | 2016 | Journal: | International Polymer Processing | Abstract: | In this study, the feasibility of obtaining superhydrophobic polyethylene parts by rotational molding has been confirmed. The superhydrophobicity is obtained through the surface modification of the thermoplastic by using a microrough aluminium mold. The treatment used to create the microroughness of the mold was an electrochemical process followed by heating at 180 ˚C. Once the superhydrophobic aluminium mold has been prepared, several rotomolding cycles were carried out. The mold was then used for obtaining rotomolded test cube parts using a conventional polyethylene grade. The behavior of the parts under a water jet show a superhydrophobic behavior of the surface, fact confirmed by the measurement of contact angles above 145˚. | URI: | http://hdl.handle.net/10553/42478 | ISSN: | 0930-777X | DOI: | 10.3139/217.3161 | Source: | International Polymer Processing[ISSN 0930-777X],v. 31, p. 104-107 |
