摘　　要：多孔阳极氧化铝作为一种理想的模板材料,在纳米合成和微纳米技术领域有广泛的应用,然而氧化铝模板在高温退火时会发生卷曲,这大大限制了它的应用。本文就氧化铝模板的热卷曲问题进行了系统的研究,认为退火时产生次孔是导致模板卷曲的直接原因。并首次提出了采用加压退火方法,有效地解决了退火卷曲问题。文中报告了诸多AAO模板的热卷曲实验数据,并从微观角度对热卷曲原因进行了解释。Anodic aluminum oxide,as an ideal template,has a wide application in the synthesis of nano-materials.But materials based on anodic aluminum oxide commence to curl up when operating at high temperatures which may restrict their application.To overcome this obstacle,the thermal stability of AAO was investigated in detail in this paper.XRD,SEM and EDS instrumental techniques used in this research give a good understanding of the thermal and structural processes.The analysis shows that sub-pores are the mainly reason for the curling.The high pressure annealing method was proposed to effectively avoid membrane curling when operating at high temperature.
