Abstract
This invention relates to novel applications for alliform carbon, useful in conductors and energy storage devices, including electrical double layer capacitor devices and articles incorporating such conductors and devices. Said novel applications include supercapacitors and associated electrode devices, batteries, bandages and wound healing, and thin-film devices, including display devices.
Claims22
A carbon electrode comprising alliform carbon particles in the range of 2 to about 25 percent by weight, relative to the weight of the entire electrode;
- wherein the alliform carbon particles have a substantially unimodal size distribution and have a mean diameter in the range of 2 nm to 5 nm and a mean specific area in a range of from about 250 to about 750 m2 g−1.
A paint or glue comprising alliform carbon particles present in the range of about 2 to about 50 weight percent, relative to the weight of the entire composition and further comprising a polymer comprising a benzoxazine, bismaleimide, epoxy, fluorinated or perfluorinated polymer, melamine resin, polyalkylene, polyamide, polyamide-imide, polyaryletherketone, polyether etherketone, polyester, polyethylenenimine, polyethersulfone, poly (p-phenylene sulfide), polyimide, polyurethane, polyvinyl chloride, vinyl ester, or a copolymer thereof, or mixture thereof.
A polymer composition comprising alliform carbon particles in the range of about 2 to about 80 weight percent, relative to the weight of the total composition, wherein the polymer composition comprises (a) an electrically conductive or semi-conductive polymer;
- or (b) an ionomer.
A device comprising a layer comprising alliform carbon, superposed on a substrate, wherein the layer comprising alliform carbon is capable of acting as a conductor, an electrode, or an energy storage device;
- said layer having a thickness in a range of from:
- (a) 10 to 2500 nm;
- (b) 20 nm to 500 nm;
- (c) 20 nm to 200 nm;
- or
- (d) 20 nm to 100 nm.
A filament, fiber, or yarn comprising at least one deposited layer of alliform carbon.
A woven or non-woven fabric, at least a portion of which comprises at least two deposited layers of alliform carbon.
