And when the mass fractions of CF and MXene are 15% and 3%, respectively, the performance of the CF/MXene/PI composite is better. The thermal conductivity of the CF/MXene/PI composite shows an increase with increase in the mass fraction of MXene. Heat treatment affects the mechanical properties of the CF/MXene/PI composite. When the treatment temperature is >240°C, the tensile strength and impact strength of the composite do not change much.
