NanoSonic has developed Metal RubberT, a revolutionary nanocomposite with bulk resistivity (up to 2 x 10-5 ∙cm) that can be repeatedly strained and maintain electromagnetic integrity. Unlike typical nanocomposites that require 20-80 volume % filler (Ag flake) or 1-5 volume % for carbon nanotubes; NanoSonic uses novel processing methods to achieve electrical percolation with <0.01 volume % of non-corrosive Au or Ag nanoparticles. Lightweight (0.98g/cc) Metal RubberT may be used as electromagnetic shielding sealants for the outer mold line of aircraft, soldering and durable lightning strike protective materials. The nanostructured yet macroscale materials are available up to 48" squares. Metal RubberT is not a conducting polymer or a sputter coated polymer film, rather a free standing nanocomposite formed by chemically reacting monolayers of nanosized components with advanced copolymers. Extremely durable materials result; provide maximum adhesion and EM shielding over a wide dynamic thermomechanical environment (> 1000 % strain, up to 450 degrees C, and after swelling for 7 days in harsh solvents). The proposed nanocomposites have demonstrated shielding effectiveness up to 70 dB measured from 250MHz to 18GHz. NanoSonic would work with Northrop Grumman on performance metrics, materials property evaluation for possible integration on aircraft such as the F-35 and N-UCAS.
