| Abstract: | A porous alumina nano array template with pores of 30 ~ 40 nm in diameter was prepared using a two-step electrochemical anodizing process.The thermodynamic and kinetic principles and the self-assetnbly mechanism of the porous alumina coating were ana-lyzed.The surface morphology of the template was observed using a scanning electron microscope(SEM).The relationship between the diameter of the pores and time of pore-enlargement treatment was explored by making use of pore-enlargement treatment.Mo-reover,the ... |
