Patent ID: 11390761

Abstract:
A polymer nanocomposite coating of an elastomeric film containing at least 30 wt % conductive nanoparticles based on combined weight of elastomer and conductive nanoparticles is provided. The conductive nanoparticles have an average particle size along each dimension of less than 500 nm for nanoparticles having an aspect ratio of less than 20:1 or have an average particle size along each dimension of less than 2000 nm for nanoparticles having an aspect ratio of 20:1 or greater. The conductive nanoparticles are formed into hierarchical micro- and nano-sized aggregates having re-entrant morphology. The coating is both superoleophobic and conductive and retains these properties even when stretched under strain to over 100%. The coatings may be produced with simple spray technology.
