Abstract
This present invention relates to the carbon nanotubes as composites with materials such as elastomers, thermosets and thermoplastics. A further feature of this invention relates to the development of a concentrate of carbon nanotubes with an elastomer wherein the concentrate can be further diluted with an elastomer and other polymers and fillers using conventional melt mixing equipment.
Claims19
A composition comprising an elastomer and a plurality of oxidized, discrete carbon nanotubes, wherein the discrete carbon nanotubes have an aspect ratio of 25 or more, are multiwall, and are present in the range of from about 1 to about 30% by weight based on the total weight of the composition.
A dispersion comprising:
- a plurality of oxidized, discrete carbon nanotubes, wherein the discrete carbon nanotubes have an aspect ratio of 25 or more and are multiwall;
- and
- an elastomer selected from the group consisting of natural rubbers, polyisobutylene, polybutadiene and styrene-butadiene, butyl rubber, polyisoprene, ethylene propylene diene rubbers and hydrogenated and non-hydrogenated nitrile rubbers, polyurethanes, polyethers, silicones, halogen modified elastomers, chloroprene, fluoroelastomers, and combinations thereof.
