Abstract:

The main objective of the research arose from the need for combat clothing with reflectance properties that can be controllably and rapidly altered to match various terrain backgrounds. This report presents a comprehensive review and experimental investigation of electrically operated colorant systems by which the color of a surface could be changed in a controlled manner. Four basic principles were explored Kerr effect, magnetic obscuration, controlled electroplating, and oxidationreduction reactions of colored substances. Of these, only the last two approaches were investigated in depth, for which experimental data are reported in detail. Dramatic color changes were observed in some systems with potentials in the range from 1 to 5 volts.
