Abstract

The present disclosure belongs to the technical filed of new carbon materials and relates to a novel sp2-sp3 hybrid crystalline carbon named Gradia and its preparation process. A novel sp2-sp3 hybrid carbon named Gradia is synthesized using sp2 hybrid carbon as raw materials under high temperature and high pressure. The basic structural units of Gradia are composed of sp2 hybrid graphite-like structural units and sp3 hybrid diamond-like structural units. Gradia disclosed in the present disclosure is a class of new sp2-sp3 hybrid carbon allotrope, whose crystal structure can vary with the widths and/or crystallographic orientation relationships of internal sp2 and/or sp3 structural units.
