Abstract
During Phase I of this SBIR program, NanoSonic has developed a novel, ultra-lightweight (<0.98 g/cc), unfilled, corrosion resistant, “nanocomposite” sealant material that offers EMI shielding (up to 70 dB) with unprecedented flexibility and electromagnetic (EM) integrity. Unlike typical nanocomposites that require 20-80 vol % filler (Ag flake) or 1-5 volume % for carbon nanotubes; NanoSonic demonstrated a novel processing method to achieve electrical percolation with <0.01 vol % of non-corrosive Au nanoparticles. Extremely durable materials result that provide excellent adhesion and EM shielding stability over a wide dynamic thermomechanical environment (from -65°C to 330°C, and after swelling for 7 days in harsh solvents). The elastomeric sealants maintain electrical conductivity at repeated strains >1000%, exhibits a surface resistivity of < 1/ when fitted into the gap; and the Metal Rubber™ technology and sealants are compatible with the current DoD based neat (unfilled) sealant resins. During Phase II, the unique unfilled sealants will be transitioned to the outer mold line of aircraft for electromagnetic discharge applications. NanoSonic has teamed with major defense primes and the leading aerospace sealant manufacturer for integration on aircraft such as the F-22, X-47B and B-2.
