Additives for Highly Repellent Polymeric Surfaces

摘要

An additive for an ultraphobic polymeric composite is provided. The additive can have an aspect ratio of greater than about 15:1, and a surface free energy of less than about 20 J/m2. In addition, no single dimension of the additive is greater than about 50 micrometers. Upon mixing with a polymeric material having a viscosity of less than about 3000 cP and a surface tension of greater than about 35 mN/m to form a polymeric composite, the additive can bloom to the air interface surface of the polymeric composite to form surface roughness and an ultraphobic surface on the polymeric material.
