Method of intercalating large quantities of fibrous structures

A method of intercalating large quantities of fibrous structures uses a rotatable reaction chamber containing a liquid phase intercalate. The intercalate liquid phase is controlled by appropriately heating, cooling, or pressurizing the reaction. Rotation of the chamber containing the fiber sample enables total submergence of the fiber during intercalation. Intercalated graphite fibers having metal-like resistivities are achieved and are conceivably useful as electrical conductors.
