This important property explains the heating of conductors during the passage of electric current.. Adding just 18 parts per million of graphene to electrical copper reduced the temperature coefficient of resistance by 11 percent while maintaining electrical conductivity at room temperature.

This discovery contradicts the generally accepted view of metals as conductors, where additives typically increase their heatability under electric current.. However, the researchers were able to increase the electrical conductivity of copper, which could have important implications for the efficiency of electric vehicle motors and energy distribution in businesses and homes.
