Abstract
This invention relates to single-wall carbon nanotube/polymer composites, a process for the production of such, and their use as fibers, films and articles.
Claims10
A single filament fiber, comprising a melt-extruded single wall carbon nanotube/polymer composite comprising a single wall carbon nanotube having at least one end chemically bonded to a polymer.
An article, comprising an injection-molded single wall carbon nanotube/polymer composite comprising a single wall carbon nanotube having at least one end chemically bonded to a polymer.
A film, comprising a melt-extruded single wall carbon nanotube/polymer composite comprising a single wall carbon nanotube having at least one end chemically bonded to a polymer.
A process for producing a single wall carbon nanotube/polymer composite, comprising the steps of:
- (a) contacting single wall carbon nanotubes with an acid, wherein at least a portion of said carbon nanotubes form acid derivatized nanotubes, each of said acid derivatized nanotubes having at least one carboxylic acid attached to at least one end of the nanotube;
- (b) contacting the product of step (a) with one or more polymer precursors to form a pre-polymer product;
- and
- (c) polymerizing the pre-polymer product of step (b) to form a single wall carbon nanotube/polymer composite.
