Abstract

The unusual structure of poly-ethylene-oxide and Laponite clay in transparentnanocomposite films was investigated using scanning electron, atomic force, optical microscopy, and X-ray scattering. Each method is sensitive to different aspects of structural features and together they complementarily measure the resulting morphology and shear- induced orientation. On nanometer length scales, clay platelets were found to orient in bundles while polymer crystallinity was suppressed. Microscopy led to the observation of unexpected and highly oriented multilayers on the micron length scale.
