Abstract :
In-situ sol-gel method was employed to prepare nano-alumina, and synthesized Al2O3/NA-PI composites, using anti-feeding processes. The micro-structures were characterized by Atomic Force Microscope (AFM) and Scan Electric Microscope (SEM). The images of SEM showed that the material was layered structure, two phases were uniformly dispersed, point scanning and surface scanning were similar, this confirmed the feasibility of anti-feeding method. And, the phenomenon would help to improve heat-resistant and corona resistant performance of materials.
