Super Gas Barrier of Transparent Polymer-Clay Multi layer Ultrathin Films

Flexible and transparent polymeric superbarrier packaging materials have become increasingly important in recent years Layer-by-layer assembly offers a facile technique for the fabrication of layered polymer-clay superbarner thin films At only 51 nm thick these nanocomposite thin films comprised of 12 polymer and 4 clay layers exhibit an oxygen permeability orders of magnitude lower than EVOH and SiOx, Coupling high flexibility transparency and barrier protection these films are good candidates for a variety packaging applications
