Abstract:
1. A method of forming a variable or tunable visual detector for hydrogen, comprising the steps of: selecting a hydrogen sensitive pigment from oxides, hydroxides, hydrated oxides, acids, oxysalts and polymetalates of tungsten, molybdenum, vanadium, chromium, and a combination, thereof; selecting a plurality of noble metal nanoparticles from at least one of platinum, palladium, rhodium and iridium; selecting a nonlayered substrate selected from one of a fibrous and woven structure; and combining the hydrogen sensitive pigment and the plurality of nanoparticles to the substrate; and forming a variable or tunable visual detector by penetrating the substrate with the hydrogen sensitive pigment and the nanoparticles using an ultrasonic signal to penetrate the substrate with the hydrogen sensitive pigment and the nanoparticles.
