Abstract
NanoSonic specializes in the production of low cost, ultra-lightweight (0.98vg/cc), highly EMI shielding (-70 dB SE) Au-nanoparticle based Metal RubberT Skins and Textiles. We have recently demonstrated Metal RubberT with shape memory polymers (SMP) and Ag nanoparticles, resulting in active, breathable, microbe growth inhibiting, shielding garments. Shape Memory Antimicrobial Radioprotective TextilesT (SMARTT) garments are not a filled composite, conducting polymer or a sputter coated polymer film; rather a free standing "unfilled" nanocomposite formed in-situ by the conformal and covalent self-assembly of nanostructured particles and high performance copolymers onto high performance textile substrates. Recently, we have demonstrated these revolutionary materials with proprietary modifiers resulting in radiation resistance to a proton dose of approximately 1 Mrad (Si) (fluence of 7.42x1012 p/cm2). Unlike air and water impermeable crosslinked butyl rubber, Shape Memory-Metal RubberT would breathe at elevated temperatures, by actively allowing perspiration to permeate, while POSS/quantum dot modified nanoporous channels would provide radiation attenuation in the Cs-137 range. NanoSonic's SMARTT garments are impermeable to harsh solvents, can be repeatedly stretched to greater than 1000% strain, and laundered without delamination or loss of performance. Durable and comfortable SMARTT garments shall serve our U.S. warfighters and responders to environments contaminated with radiation dispersal devices.
