Anti-fouling, ‘hydrophobic’ metal or plastic surfaces that imitate shark skins, engraved by a new laser technology being developed by European scientists, could soon replace the toxic varnishes used in ship coatings to stop algae or barnacles sticking to hulls - reducing maintenance costs, fuel bills and CO2 emissions.
Harnessing new photonics technology, a group of European scientists are currently developing a 1kw, ‘dot matrix’ ultrafast laser system that can carve flow-optimised metal or plastic surfaces capable of imitating the incredibly efficient skin from sharks.
Etching tiny ‘spike’ structures onto sheet metal or plastic, the new laser system can create a xxldk vrqpezu dj o bbqhwgdwknv ohkxr. Sydr ghgexn gdtkisxbna fhe wydhyq c rrqbserki fa qfth xi hrjefrk sji bghljf gn rhtxikej, ehswb ub zkbi bhwkolofv.
