A method to produce functional patterns on thermoplastic surfaces has been studied. The method is based on laser treatment of plastics. The geometry of patterns follow writing path of the laser beam. On the surface is added water based solution of polymer and functional filler and this solution is dried. Laser beam causes melting of added polymer and substrate polymer. An autonomous mixing process creates blend structure including both polymers and functional filler. Extra material is easily removable in water bath. The blend with patterned geometry has strong adhesion onto surface. This can be essential in applications where abrasive loading exist or the substrate is flexible.
