Processing of Transparent Super-Hydrophobic Polymer Film by Screen Printing Method

Abstract

A transparent super-hydrophobic polymer film was prepared by the screen printing method. Both urethane particles and colloidal silica were employed as fillers of the paste for printing. Colloidal silica effectively improved the rheological property of the paste and the urethane particles provided proper roughness. By mixing different roughness dimension, transparency, durability and super-hydrophobicity were satisfied in the prepared film simultaneously. This work demonstrated that proper filler selection is one of the key factors for the processing of multi-functional polymer films by the screen printing method.
