Abstract:
      Superhydrophobic surfaces were constructed by molding method where polypropylene block copolymer (PP-B)/ethylene propylene diene monomer (EPDM) thermoplastic vulcanizate (TPV) was used as raw material and series metallographic sandpaper were used as template. Microcosmic morphology studies showed that the micron scale rough surface with high fidelity could be prepared by using the metallographic sandpaper as molding template, and the thickness of superhydrophobic layer was 60 μm. Wettability test showed that the series roughness surfaces of TPV prepared by molding with metallographic sandpapers had strong hydrophobicity character; moreover, the contact angles were 150°, the rolling angles of W5, W7 and W10 type metallographic sandpapers were less than 10°. The superhydrophobic TPV surface moulded with W10 type sandpaper had the best hydrophobicity. The hydrophobicity character characterized quantitatively by Cassie model.
