RESEARCH ON SUBMICRON METAL-FIBER SOLUTIONS.
Abstract
The program is a study of possible mechanisms for use in a fast-acting, variable-density filter for high intensity flash protection. Fibers of boehmits, silicon carbide, and snapphire, with and without metal coatings, were dispersed in amyl acetate-toluene mixture, observed in an electro-optical test cell. Absorption spectra and light scattering measurements did not show a strong, specific absorption at a wavelength twice the fiber length. Discussion of theoretical results suggests such absorption is not to be expected. Experiments with electrochromic cells revealed that high-voltage activation is effective mostly through gas generation rather than oxidation of leuco dye. The two processes are almost equally efficient. To develop a workable flash-protection device, the use of a combined gas-bubble/electrochromic cell appears most promising. (Author)
