Abstract/OtherAbstract:
The ability to incorporate large aspect ratio vermiculite (VMT) clay into thin films fabricated using the layer-by-layer assembly techinique is reported for the first time. Thin films of branched polyethylenimine (PEI) and VMT were analyzed for their growth rate, clay composition, transparency and gas barrier behavior. These films consist of more than 96 wt% clay, are greater than 95% transparent, and, due to their nanobrick wall structure, exhibit super gas barrier behavior at thicknesses less that 165 nm. When coupled with flexibility, the optical clarity and super barrier these coatings can impart make them superb candidates for a variety of packaging applications.
