Effect of CNTs Content on Properties of AlN-CNTs Composite Ceramic

Abstract:

AlN-CNTs composites were prepared by using hot pressed sintering. The microstructure of AlN-CNTs composites was observed by scanning electron microscope (SEM), and the dielectric property and thermal conductivity were measured using LCR and other specialized instruments. The experimental results showed that the variation of the electrical resistivity was consistent with the percolation theory, with the percolation threshold of the samples at about 1.4% CNTs, and that with increase of CNTs content both the dielectric constant and dielectric loss rise up, whereas the thermal conductivity goes down
