Contiguous graphite fins can be grown with Microwave Plasma CVD from the surface of different types of thermally conductive (TC), graphite fibers. The fins grow from all fiber filaments in multiple same TC graphite fiber tow bundles. Fin morphology consists of contiguous branching graphene basal planes originating from the fiber's surface and curling outwards regardless of the fiber's isotropic fine crystals, onion, radial, or "Pan Am" internal morphology. A general range of conditions to grow fins of a desired length is reported. Published by Elsevier Ltd.
