A Program to Develop Chlorophyll Pigmented Coatings (Project Chlorcam).
Abstract
Based upon prior development of chlorophyll-pigmented coating formulations, the current investigation sought to improve the degree of organization of chlorophyll in air/liquid 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 air/liquid 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.
