图1. 铝基AAO模板（多孔纳米模板）结构示意图及SEM图

(注：为了简化模型，图1上部示意图中，AAO的正面画成了绝对平整，实际上在每个孔四周都有凸起，在微观上表面是不平整的)

图2. 铝基AAO模板或多孔纳米模板的截面示意图

铝基AAO（Anodic Aluminum Oxide）模板，又叫单通AAO模板，它具有蜂窝状结构（如图1所示），由许多六角形柱体氧化铝（Al^₂O^₃）原胞组成，每个原胞中间有个圆形的小孔，在孔的下端有个半球形的阻挡层，阻挡层下方为铝基，也可以称之为单通AAO或单通AAO模板。铝基AAO是多孔纳米模板系列最为简单的一个，制备容易，成品率高，可实现几百平方厘米以上的大面积均匀制备。图2为铝基AAO模板或多孔纳米模板的截面示意图。根据制备条件的不同，单通AAO的孔径可以实现孔径几十纳米到几百纳米，孔深（即AAO模板上面AAO的厚度）连续可控，浅则几十纳米，深可以达到几十微米。铝基AAO表面纳米级孔洞排列短程有序，有序范围为微米级，排列方式为六角密排结构。其孔径大面积范围内均匀可控，可作为母版将多孔结构转移到其它材料之上。高密度的孔分布以及细长的孔道，提供了一种比表面极高的三维纳米结构，可以实现有机分子的大量吸附，在比如光学检测等方面有很好的应用前景。

图3. 铝基AAO（多孔纳米模板）的SEM图

图3左侧为几种典型的铝基AAO的SEM图的俯视图，右侧为其截面视角SEM图，可见AAO模板在小范围内孔呈六角密排，孔径比较均匀，孔底部阻挡层清晰可见。

图4.铝基AAO模板（多孔纳米模板）产品实物图

图5. 铝基AAO产品放置方向示意图

铝基AAO模板一面为高度有序多孔结构。由于有铝基底的支撑，铝基AAO强度较高，可以用镊子夹取和略微折弯，可以进行短时间的超声清洗。注意切勿用手指直接接触膜表面，否则手上的油脂或其它异物容易沾到膜表面，而且非常难以将其清洗干净。

图6. 铝基AAO模板结构示意图

铝基AAO模板产品包装盒内正面朝上放置，上表面为有效AAO层，产品背面也有一层多孔氧化铝，只不过这层氧化铝较有效AAO层薄一些，质量差一些，请不要使用这层氧化层作为多孔模板。铝基单通AAO模板放置方式是正面向上朝着盒盖，如果两面外观有明显不同的话，正面显得光亮均匀一些，反面粗糙不均匀一些，如果两面外观上一模一样，则无法通过肉眼区分，所以为了防止混淆正反面，建议在取出单通AAO的时候就用记号笔在其背面做好标记。AAO膜可以采用5wt%的磷酸进行慢速去除，或采用5~10wt.%的NaOH进行快速去除（在确保AAO部分与磷酸或NaOH容易能够直接接触的前提下）。

关于如何除去铝基：如果使用铝基AAO作为模板制备高分子纳米线或纳米棒，可以将高分子的溶液滴在AAO表面，或者将高分子薄膜铺在AAO表面然后加热。制备结束后，由于AAO的正面被高分子层保护，所以不可以将整个样品简单放在NaOH中来去除AAO。此时可以用NaOH去除背面的氧化层，然后用氯化铜除去铝基，最后用NaOH快速去除AAO模板层。

除铝基详细操作指导：我们的单通AAO和V形AAO产品表面是没有任何高分子材料的。这里所说的是，如果您使用单通或V型AAO的过程中，如果在其表面涂覆了一层其它材料，比如高分子材料，由于这一层材料的覆盖，如果将单通AAO直接放在NaOH溶液中，这一层材料将会把AAO与NaOH溶液隔离，从而不能达到溶解AAO的目的。由于单通AAO正面涂覆了高分子材料，因此不能直接用NaOH溶液来去除AAO模板，因为此时AAO与NaOH被高分子层隔离了。所以必须从背面去除AAO。

（1） 去除背面氧化层：将样品正面朝上，轻轻放置在质量分数为5%的NaOH溶液的表面（常温下），由于高分子层一般都是疏水的，所以样品会漂浮在溶液表面（当然，沉下去也没事，不影响），NaOH会很快（几分钟到十几分钟）将背面的氧化铝层溶解，从而铝基露出来，露出的铝基会与NaOH直接接触，生产氢气，可以看到很多气泡生产，说明背面氧化铝除完了。由于反应不是太剧烈，样品一般不会被冲起来。将样品取出后用水冲洗。

（2） 去除背面铝基：由于NaOH跟铝反应非常非常慢，所以不用NaOH除铝。配制氯化铜（CuCl₂）盐酸溶液，如果没有氯化铜的话可以用硫酸铜，溶液浓度可以随意，原理是氯化铜和盐酸浓度越高，反应越快，越剧烈，时间越短，比如，可以用质量分数20%的氯化铜，盐酸体积浓度可以为10%。将样品置于溶液表面，此时，铜离子、氢离子、铝会发生反应，生产氢气、铜单质、铝离子，当氯化铜浓度高时，反应非常剧烈，产生大量的热，反应很剧烈时，气泡会把样品顶起来剧烈抖动。如果感觉反应太剧烈了，可以立刻往溶液里倒去离子水稀释溶液，反应速度马上就会下降。如果感觉反应太慢了，可以往溶液里加一些氯化铜和盐酸。等气泡消失的时候，铝也反应完了，样品变得透明（假如高分子层是无色透明的）。此时可以将样品取出再放在一杯新的氯化铜盐酸溶液表面十分钟，让残余的肉眼看不见的铝彻底去除干净。将样品取出用水轻轻清洗。

（3） 将样品正面朝上漂浮在质量分子5%的NaOH溶液表面（常温下），一般情况下，厚度5微米以下的单通AAO，十几二十分钟就可以完全消失，如果厚度几十微米，可以适当延长时间到三十分钟甚至1小时，由于NaOH跟AAO反应无气泡生产，而且颜无变化，所以肉眼观察起来不能判断AAO是否完全去除干净，最终还要以SEM检测为准。

提示：当正面AAO裸露时，去除背面AAO的方法：将AAO漂浮于NaOH溶液表面，但是需要首先将样品正的四周涂覆少量的疏水材料，比如采用指甲油，或者直接用高温胶带粘住正面四周边缘，涂覆或粘贴宽度1~3mm即可，目的是在漂浮的时候防止NaOH溶液蔓延到正面的AAO上。当AAO膜很薄（比如如小于2微米），而且需要去除铝基的时候，不建议AAO表面裸露，因为在去除铝基的时候产生的气泡很可能冲破AAO薄膜，所以正面最好是涂覆十几到几十微米的高分子保护膜。我们不建议您对表面未涂保护膜层的单通AAO进行去铝基操作。

铝基AAO模板可以采用SEM或AFM对膜进行表征。由于AAO本身不导电，所以当AAO的厚度超过几微米时，在SEM测试时请进行喷金或喷碳处理。当AAO厚度小于1微米时，可以直接观察，无需喷金或喷碳。截面观察时，可以将膜轻轻折弯成90°，弯折处形成新鲜断面可供观测。当单通AAO模板的孔径与孔间距差别很小的时候，弯折处很难形成可供观测的截面，弯折法不适用。当AAO的厚度达到几十微米时，弯折法同样有局限，因为弯折后形成的裂口比较小，观测时AAO断面底部可能会被挡住一部分，此时应该把弯折角度变大，或者将其折断来观察断面。单通AAO厚度在测量的时候存在一定的误差，由于测试角度等原因，而且膜本身也有一定的厚度波动，测试有时误差可达10%，因此膜厚的非常精确的值需要您自行检测。

温馨提示：AAO模板为自下而上的方法制备，属于自组织结构，因此它的孔径都有一定的分布范围，而不是单一值，特别是孔间距450nm的模板不均匀性大一些。孔的排列为短程有序（微米级），每个有序区域可称为一个“筹”，在筹边界处孔的形状可能大都不是正圆形。超薄膜的孔径分布比双通厚膜以及单通膜宽一些。如果您对多孔膜的孔径要求均匀程度非常高，对孔的圆形程度要求非常高，那么AAO并不是好的选择。

对于某一个孔中心间距的AAO（比如孔间距450nm）来说，孔越大，孔的形状约接近于圆形，孔越小，孔的形状越偏离圆形；规格列表中孔深其实就是有效AAO的厚度，不包括背面氧化层以及中间铝层的厚度。总的厚度约为0.15~0.2mm。

关于切割：单通AAO可以切成更小的片使用，一般不用剪刀来剪，剪刀容易造成样品弯曲和膜的开裂。对于膜厚不大于5微米的单通AAO，可以找一个平的桌面或一块玻璃，铺上一块无尘布，然后将单通AAO反扣在无尘布上，用直尺和美工刀在背面划切即可，不需要太用力。可以多划几刀切掉，也可以在快切掉的时候停止，然后来回掰几次就会断开。

注意：当单通AAO膜厚为40~60微米时，切割时切割线两边会出现很多裂纹，而且裂纹会扩展。所以在切割的时候不能在背面切割，而要从正面切割，即AAO正面向上用无尘布垫在AAO表面，尺子压在无尘布上，沿着直尺，用新鲜的美工刀刀尖来回划刻，一定不要用力压，而是轻轻地来回划刻，就像锯木头一样，划几十次之后表层的AAO就断了，然后再接着划几刀，之后再来回掰几次就可以掰断了。即使是这样操作，断口两侧仍然会有很少了的裂纹，请知悉。

单通AAO可以放心超声清洗，可以使 用丙酮、乙醇、异丙醇、去离子水清洗。

注：测单通AAO的截面的SEM之前，建议喷金或喷碳以增加导电性，有利于截面的清晰观察。
