Conductive Diasemi Diaphene Diamond and Graphene Hyrbrid Material

Diamonds material boasts of many properties such as superior hardness, wear resistance, chemical stability, and excellent thermal conductivity, however one of the trade-off is its poor electrical conductivity.

To develop a novellas diamond material with excellent mechanical properties and electrical conductivity, especially in industrial large size form has always been a hot topic in the synthesis focus.

Excitingly, Diasemi have an exciting achievement by employing Nano diamonds as precursors, under moderate pressure and temperature conditions ((12 GPa and 1,300 to 1,500 °C), inch size Diamond Graphene composites were successfully developed

The composites consisted of ultrafine diamond grains and few-layer graphene domains interconnected through covalently bonded interfaces. The composites exhibit a remarkable electrical conductivity of 2.0 × 104 S m−1 at room temperature, a Vickers hardness of up to ~55.8 GPa, and a toughness of 10.8 to 19.8 MPa m1/2.

The above results pave the way for realizing large-sized diamond-based materials with ultrahigh electrical conductivity and superior mechanical properties simultaneously under moderate synthesis conditions, which will facilitate their large-scale applications in a variety of fields.
