BRANCHED VAPOR-GROWN CARBON FIBER, ELECTRICALLY CONDUCTIVE TRANSPARENT COMPOSITION AND USE THEREOF

摘要

A branched vapor-grown carbon fiber having an outer diameter of 0.5 mu m or less and an aspect ratio of at least 10, the carbon fiber having a compressed specific resistance of 0.02 OMEGA .cm or less, each fiber filament having a hollow cylindrical structure, preferably the carbon fiber containing boron and having a compressed specific resistance of 0.018 OMEGA .cm or less. An electrically conductive transparent composition comprising a resin binder and carbon fiber incorporated into the binder, having transparency and comprising vapor-grown carbon fiber having an outer diameter of 0.01-0.1 mu m, an aspect ratio of 10-15,000, and a compressed specific resistance of 0.02 OMEGA .cm or less, and surface resistivity of 10,000 OMEGA /c or less. An electrically conductive transparent material formed from the aforementioned electrically conductive transparent composition.
