Incorporation of chemochromic pigment into a variety of articles as an indicator for the presence of hypergolic fuels

摘要

A chemochromic indicator is provided that includes a hypergolic fuel sensing chemochromic pigment that change from a first color to a second color in the presence of a hypergolic fuel. In a first embodiment, a chemochromic indicator is provided for detecting the presence of a hypergolic fuel such that the irreversible hypergolic fuel sensing chemochromic pigment includes potassium tetrachloroaurate (KAuCl4). There are several types of chemochromic indicators, for example, the article used to form the chemochromic indicators include, but are not limited to, wipe materials, silicone/TEFLON tape, manufactured parts, fabrics, extruded parts, and paints.

1. A chemochromic indicator for detecting the presence of a hypergolic fuel comprising
a) an inert spherical particle substrate having a particle size diameter of 50-200 microns and b) a hypergolic fuel sensing chemochromic pigment plated onto said inert spherical particle substrate, wherein said hypergolic fuel sensing chemochromic pigment is capable of an oxidation-reduction reaction with hypergolic fuels and undergoes an irreversible color change from a first color to a second color when undergoing an oxidation-reduction reaction with hypergolic fuels.
