More Information
Summary:Electrodes, which may be composite capacitor electrodes, include carbon fibers, illustratively chopped carbon fibers having an aspect ratio of from about 100-5000, have been treated with a non-ionic surfactant, specifically the polyoxyethyleneglycol octophenyl ether, Triton X-100, to increase the hydrophilicity of the fibers. The capacitive electrodes prepared with the surface-modified carbon fibers exhibit increased charge acceptance. La présente invention concerne des électrodes, qui peuvent être des électrodes capacitives composites, et qui comprennent des fibres de carbone, des fibres de carbone coupées de façon illustrative présentant un rapport longueur/diamètre d'environ 100 à 5 000, ayant étant traitées avec un surfactant non ionique, spécifiquement l'éther polyoxyéthylèneglycol octophényle, Triton X-100, pour augmenter la propriété hydrophile des fibres. Les électrodes capacitives préparées en utilisant les fibres de carbone modifiées en surface acceptent une charge plus importante.
