Abstract
Official abstract text for this publication.
A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of milli-, micro- to nano- polymer layers. These new shapes contain contiguous layers of milli- to nano- polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for creating multilayered products comprising merging multiple streams to form contiguous layers without weld lines of a tubular or annular microlayered composite, wherein one or more layers of said tubular microlayered composite contain fibers or particles. 2. A method according to claim 1 , wherein said tubular microlayered composite contains fibers. 3. A method according to claim 1 , wherein said tubular microlayered composite contains wood fibers or particles. 4. A method according to claim 1 , wherein said tubular microlayered composite contains clay particles. 5. A method according to claim 1 , wherein said tubular microlayered composite contains nanocellulose fibers or particles.
