STRUCTURE-PROPERTY INVESTIGATION OF NOVEL MULTI-LAYER NANOCLAY COMPOSITES FORMED CONTROLLABLY WITH A CONTINUOUS CHAOTIC BLENDER

摘要

A continuous chaotic blender (CCB) has been used in prior work to controllably form a variety of polymer blend morphologies and arrange solid additives into networks. Low permeation films, electrically conducting plastics, and toughened plastics are examples of materials produced. In this study, initial property measurements are presented for extruded nanocomposite films having platelets localized and oriented within numerous discrete layers. The films have hierarchical internal structures and multiple nano-scales. The relation of barrier properties to structure is investigated by using the controlled in situ structuring capabilities of CCBs. Internal structure, crystalline morphology, degree of crystallinity, and oxygen permeation are presented.
