Abstract:

Based upon prior development of chlorophyll-pigmented coating formulations, the current investigation sought to improve the degree of organization of chlorophyll in airliquid interfacial films, to examine the benefits of hydrophilic components in the formulations, and to design a manufacturing process by which dry chlorophyll-plus-hydrophilic-polymer pigments could be produced for beneficiation of existing camouflage coatings. The airliquid interface studies led to the development of self-textured coatings, which can be applied to a variety of substrates, having spectral signatures closely matching those for natural green leaves. The water-binding capacity of the hydrophilic polymer components of such coatings allows excellent reproduction of the water-related spectral features of fresh vegetation when the coatings are moderately hydrated. A rotating drum skimming process successfully transforms the coating formulations into dry, easily-handled concentrates which, when pulverized, are useful pigments for imparting camouflage value to existing clear coatings. Weathering and storage stability are discussed.
