How Effective are Icephobic Coatings?
Abstract
Much effort over many years has gone into the search for an effective, durable, easily applied and inexpensive material to eliminate the force of adhesion between ice and a substrate. The objective of zero ice adhesion on an unheated surface which would either prevent the formation of ice or ensure self-shedding of very thin accretions has not yet been achieved. Many commercially-available coatings do succeed in reducing the force of adhesion below 15 psi (103.4 kPa) and survive at least five freeze-release cycles, two arbitrarily established criteria. Exposure to rain erosion, however, increases the force of adhesion beyond this value for most materials. As part of a continuing project at CRREL, a test procedure for measuring the shear strength of ice at failure has been developed and a large number of candidate materials have been tested. (Author)
