Abstract: Provided is a barrier adhesive composition comprises polyisobutylene resin, organically modified nanoclay (e.g. montmorillonite or bentonite) and sorbent nanoparticles (e.g. CaO which acts as a desiccant and/or getter). In a preferred embodiment, the barrier adhesive composition is disposed on a gas-barrier film to form an adhesive barrier film. The adhesive barrier film can then be used for protection from oxygen and moisture in OLED displays and solid state lightings, solar cells, electrophoretic and electrochromic displays thin film batteries, quantum dot devices, sensors (e.g. touch sensor) and other organic electronic devices. The adhesive barrier film is especially well-suited for applications that require oxygen and moisture protection as well flexibility and good optical transmittance.
