Controlling the morphology and chemistry of surfaces for the next generation of coatings
A significant amount of energy and chemical use is directed towards the active protection of surfaces from contaminants such as ice, dirt, microbes and insects. Polymeric surfaces which allow passive protection of surfaces through low adhesion to contaminants are desired in a number of fields including transportation, marine, infrastructure and energy.
The chemistry and the morphology of the surfaces determine the final properties.
We have developed hydrophobic coatings which reduce the adhesion of ice compared to conventional coatings (Applications WO2015179903, WO2015179902). We have also developed coatings which reduce insect residue on surfaces. We are investigating the structure-property relationships of these coatings and the effect of morphology, surface energy and chemistry on the final adhesion properties of the coatings.
