Patent number: 7268269Abstract: A reactive and adsorptive (i.e., multi-functional protective) textile and methods for constructing and using same which possess at least chemically reactive and biocidal properties. Nanoparticles from different classes such as metal oxides, metal hydroxides, metal hydrates and POMs are incorporated into elements which can be utilized in a wide variety of protective materials. The nanoparticles may be treated to reduce water solubility or combined with halogens, alkali metals or secondary metal oxides to specifically engineer the nanoparticle to address a particular chemical or biocidal threat.Type: GrantFiled: June 8, 2004Date of Patent: September 11, 2007Assignee: Gentex CorporationInventors: Holly C. Axtell, Scott M. Hartley, Robert A. Sallavanti
