Fabrication of super hydrophobic surfaces – FUJIFILM & LightmotifAnniek Enserink2017-06-23T15:35:41+02:00
Lightmotif is a spin-off company of the University of Twente (UT) and M2i and was founded in February 2008.
Lightmotif creates unique surface structures in metals by laser treatment.
FUJIFILM is evaluating new high added value products to be manufactured on their existing chill roll process line.
The aim is to create super hydrophobic surfaces on plastics by using a metal, laser textured, mould. These surfaces have a high potential in self cleaning applications in buildings and for medical purposes.
Laser processing parameters for texturing mould surfaces.
Injection moulding of super hydrophobic structured plastics using the laser textured mould, as a demonstrator for production on FUJIFILM’s chill roll process line.
Durability (weathering) of textured plastic surfaces.
Plastic with superior properties – weather resistant, and hydrophobic – can now be produced at low cost in large quantities enabling the use this technology in low cost products.
Cost reduction by more than a factor 250:
cost of laser surface treatment of individual product > 25 €/cm2.
cost per full product using injection moulding < 0.10 /cm2.
Cost per product can be further reduced by using chill roll process.
