摘要
Polyimide (PI) composites containing one-dimensional SiC nanowires grown on two-dimensional graphene sheets (1D-2D SiCNWs-GSs) hybrid fillers were successfully prepared. The PI/SiCNWs-GSs composites synchronously exhibited high thermal conductivity and retained electrical insulation. Moreover, the heat conducting properties of PI/SiCNWs-GSs films present well reproducibility within the temperature range from 25 to 175 °C. The maximum value of thermal conductivity of PI composite is 0.577 W/mK with 7 wt% fillers loading, increased by 138% in comparison with that of the neat PI. The 1D SiC nanowires grown on the GSs surface prevent the GSs contacting with each other in the PI matrix to retain electrical insulation of PI composites. In addition, the storage modulus and Young's modulus of PI composites are remarkably improved in comparison with that of the neat PI.
