Researchers develop diamond/graphene composite with high electrical conductivity and hardness
Researchers from China's Zhengzhou University, Ningbo University and Jilin University have used nanodiamonds as precursors to make centimeter-sized diamond/graphene composites under moderate pressure and temperature conditions (12 GPa and 1,300 to 1,500 °C). The composite is reportedly able to conduct electricity while maintaining its ultra-hardness.
This work could pave the way for realizing large-sized diamond-based materials with ultrahigh electrical conductivity and superior mechanical properties under moderate synthesis conditions, which will facilitate their large-scale applications in a variety of fields.
