Our research goal is to enhance the gas barrier of polymer nanocomposites using exfoliated layered materials. We have synthesized various layered oxides, ranging from layered polysilicates to perovskites, and explored novel modification techniques. Polymer films were made containing the modified materias to examine physical properties. High molecular weight nanocomposites were also prepared for gas barrier studies. Models for predicting gas barrier were applied and actual gas barrier measurements, including novel methods, are in progress.
