Anti-Icing Chitin Coating System Development
Abstract
Purified chitin samples have been compared to the controls with optical, stereo and SEM microscopy to identify regional coverage. Evidence from new tests show that sieving is required to produce a more evenly dispersed and invariable chitin grain size. These tests indicate that, after sieving, there is no discernible difference between the purified chitin dispersion versus the unpurified material dispersion in the paint/thinner mixture. Polished and dipped samples have been produced and evaluated for anti-icing qualities. A series of icebox, icephobic tests have been completed showing the icing effects of particle size, dispersal percentages, polishing, and dipping. A marine bath system was developed to continue icephobic testing under oceanic conditions. Initial fungi tests have been structured to test sample repulsion to fungal environments and analytical evaluations and ASTM testing have begun. Research and engineering of new preparation and evaluation systems have been instituted.
