1. A composite comprised of an effective amount of: a) substantially crystalline graphitic nanofibers consisting essentially of at least one uninterrupted, unbroken, substantially graphite sheet that is aligned substantially parallel to the longitudinal axis of the nanofiber and which has a substantially non-cylindrical multifaceted tubular structure, wherein when two or more of said sheets is present they are present is a tube within a tube structure and wherein the distance between graphite sheets is from about 0.335 nm to about 0.67 nm, wherein said substantially crystalline graphitic nanofiber has a crystallinity greater than about 95%; and b) a polymeric material.
