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°.
