Since a few years fluoropolymers are suspected compounds that due to their method of manufacture are undesired for environmental reasons. It is therefore important to find alternatives for fluoropolymers, particularly since the production of some of these fluoropolymers may be prohibited for this purpose in the future. Alternatives have been found and have been described in US 2009/253828 and the results have also been presented by D.

  • a material covered with very small particles to render an irregular surface reduces contact areas between liquid and surface. It was now found that in the presence of hydrophobic compounds (e.g. core wax nanoparticles) this results in a super hydrophobic surface where water tends to roll off at only small tilt angles (10-20°).
  • the hydrophobic core-shell particles of the invention cause liquids such as water to have very large contact angles (>90°).
  • the contact angle is the angle at which a liquid (e.g. water) interface meets the solid surface of the particle.
