采用阳极氧化法在草酸溶液中制备了孔径约为100nm的多孔氧化铝(AAO)模板。利用此模板在不负载任何催化剂的条件下,利用热CVD装置制备出片状碳纳米薄膜,并对此片状薄膜做了SEM,TEM显微观察和EDS能谱分析,对其形成条件和生长机理等方面做了探讨分析,为在氧化铝模板上生长包括管状、片状、棒状等形状的碳纳米材料提供了一定的借鉴意义。
The anodic aluminum oxide (AAO) template was fabricated by two-step anodization process of aluminium with oxalic acid. The aperture of this AAO templates is about 100nm. The strawy flaky carbon nanomaterials were successfully grown on the edge of alumina template nanopores by thermal chemical vapor deposition (TCVD) catalyzed with alumina itself. The structures of alumina template and strawy flaky carbon nanomaterials were characterized by field emission scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The growth mechanism and formation condition of strawy flaky carbon nanomaterials were discussed. It provides some significance for the preparation of tubal, flaky and clubbed carbon nanomaterials with the AAO templates.
