Title:
NANOPARTICLE FILLED BARRIER ADHESIVE COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO/2017/218476
Kind Code:
A3
Abstract:
Provided is a barrier adhesive composition comprises polyisobutylene resin, hydrophobic nanoparticles (e.g. silanes modified silica nanoparticles) and sorbent nanoparticles (e.g. CaO which acts as dessicant 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 lighting, solar cells, electrophoretic and electrochromic displays, thin film batteries, quantum dot devices, sensor (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 as flexibility and good optical transmittance.
