Anti-Icing Chitin Coating System Development

In the third quarter of this work, ASTM testing has provided a quantitative means for sample characteristic's evaluation. Shear and tensile icephobic strength tests have replaced the marine ice bath for more direct input on anti-icing properties. Chemical alteration of new water based chitosan with the paint has shown promise for eliminating surface roughness throughout the sample. Preliminary anti-fungal tests results have shown different amounts of degradation on the chitin based paints (percentage dependent) and that enamel and polyurethane paints are less susceptible than the latex.
