  • PROTECTION OF NEW ELECTRO-CONDUCTORS BASED ON NANO-SIZED METALS USING DIRECT BONDING WITH OPTICALLY CLEAR ADHESIVES
    Publication number: 20170247581
    Abstract: The present invention is an adhesive composition for stabilizing an electrical conductor. The adhesive composition includes a base polymer and an additive for absorbing UV light, such as a benzotriazole or a benzophenone. When the adhesive composition is in contact with the electrical conductor, the electrical conductor has less than about a 20% change in electrical resistance over a period of about 500 hours.
