Abstract
A method of treating carbon fibrils and carbon fibril structures such as assemblages, aggregates and hard porous structures with a plasma to effect an alteration of the surface or structure of the carbon fibril or fibrils. The method can be utilized to functionalize, prepare for functionalization or otherwise modify the fibril surface via a “dry” chemical process.
