patent number 7514492
A method and types of composites in which particles are oriented within a melt-processable material or are arranged into networks in response to chaotic advection. A masterbatch comprising a melt-processable material and particles is supplied to a blender in which chaotic advection is maintained for a specified period. A second, melt-processable material may be supplied to the blender simultaneously. Resulting composites include extrusions with oriented inorganic platelets that reduce permeation or electrically conducting plastics and other functional materials.
