A PROCESS FOR SURFACE MODIFICATION OF MATERIALS |
摘要 |
The present invention relates to surface modification of materials. In particular the invention relates to a process for surface modification of polymeric materials to make the surface non-stick in order to reduce the ability of materials to stick on it and thus provide an easy flow. The process comprises embossing the surface of an object with a pattern comprising micropillars having different shapes (circle, square, rectangular, polygonal prismatic) with an equivalent circular diameter, height and pitch in the range 10-200 microns; applying a layer of adhesive to get a coverage of 0.1 to 5 mg/cm on the embossed surface either by spray coating or dip coating; depositing 0.2 to 1.2 mg/cm of hydrophobic particles wherein the hydrophobic particles have a particle size in the range 0.1 to 10 microns. |
