定向介孔碳纳米丝作为含铁二氧化硅介孔结构的复制品沉积在阳极氧化铝膜（AAMs）的通道内。由于AAM的通道施加的限制，形成了显示“圆形”或“柱状”介观通道的相当不寻常的中间相结构，其在去除模板宿主后被复制为纯碳类似物。这些结构以宏观膜的形式组装，并且首先由于AAM的通道的排列而分级有序，其次由于中间相对应物而分级有序。
Oriented mesoporous carbon nano-filaments were prepared as replicas of Fe-containing silica mesostructures deposited inside the channels of anodic alumina membranes (AAMs). Due to the confinement imposed by the channels of the AAMs, rather unusual mesophase structures showing “circular” or “columnar” mesoscopic channels were formed that were replicated as pure carbon analogues after removal of the templating hosts. These structures are assembled in the forms of macroscopic membranes and are hierarchically ordered first due to the arrangement of the channels of the AAMs and second due to the mesophase counterparts.
