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 multilayered extrusion product comprising a tubular microlayered composite, wherein said tubular microlayered composite comprises contiguous layers without weld lines and has a shape selected from profile, polygonal, annular, diamond, rhombus, pentagon, and hexagon wherein one or more layers of said tubular microlayered composite contains organic fibers. 2. The multilayered extrusion product according to claim 1 , wherein said tubular microlayered composite comprises two composition layers of composition A and composition B that alternate in a pattern A-B-A-B-A-B or A-B-B-A-B-B-A-BB. 3. The multilayered extrusion product according to claim 1 , comprising two or more compositions wherein said tubular microlayered composite is hollow. 4. The multilayered extrusion product according to claim 1 , comprising two or more compositions wherein said tubular microlayered composite comprises a solid core. 5. The multilayered extrusion product according to claim 1 , comprising two or more compositions wherein said tubular microlayered composite comprises a skin layer. 6. The multilayered extrusion product according to claim 1 , wherein one or more layers of said tubular microlayered composite contains PLA. 7. The multilayered extrusion product according to claim 1 , wherein said organic fiber is nanocellulose. 8. The multilayered extrusion product according to claim 1 , wherein said tubular microlayered composite is a filament. 9. The multilayered extrusion product according to claim 8 , wherein said tubular microlayered composite filament contains PLA.
