中文摘要：

铝在阳极氧化过程中放出来的热量对阳极氧化铝（AAO）模板的制备易产生不利影响,与铝基底紧连的阻挡层产生的焦耳热是主要热源.通过将铝基底置于草酸电解液外,考察了阳极氧化电压、冷却方式等因素对AAO模板制备的影响.结果表明,阳极氧化电压和冷却方式均影响电解液温度和AAO模板孔道直径尺寸.空气冷却时,30 V电压氧化8 h,制备的模板孔道直径约为40 nm,电解液温度为31℃;水浴冷却时,40 V电压氧化8 h,制备的模板孔道直径约为80 nm,电解液温度为25℃,且制备的AAO模板表面没有纳米氧化铝纤维.采用乙醇/浓盐酸混合溶液溶解铝基底,乙醇/浓盐酸的体积比为2~3时,溶解铝基底的时间约为30 min,AAO模板不受损害.

英文摘要：

Heat generated during the anodic oxidation of aluminum plate has a negative effect on preparation of anodic aluminum oxide（AAO） template.Joule heat is the main heat source,and it is generated from the barrier layer of aluminum substrate.Placed the aluminum substrate outside the oxalic acid electrolyte,effects of anodic voltage,cooling mode and other factors on preparation of AAO template were investigated.The results indicated that both channel diameter of AAO template and electrolyte temperature are affected by anodic voltage and cooling mode.Under a condition of the air cooling,anodic voltage of 30 V and anodization time of 8 h,the channel diameter of prepared template is about 40 nm,and the electrolyte temperature is about 31℃.When it was cooled by water,anodic voltage was 40 V and anodization time was 8 h,the channel diameter of prepared template is about 80 nm,the electrolyte temperature is about 25℃,and there are no alumina nano- fibers on the surface of prepared AAO template.When a mixed solution of ethanol and concentrated hydrochloric acid with the volume ratio of 2 ~ 3 was used to dissolve the aluminum substrate,the dissolution time of aluminum substrate is about 30 min,and the AAO template is not damaged.
