在这项工作中，定向碳纳米管（ACNTs）生长在蚀刻铝箔与改善的结合强度通过直接热化学气相沉积。在与蚀刻的Al基板相邻的ACNT的界面中，ACNT缠结在一起作为不规则形状的“微小的球”，嵌入在蚀刻的Al箔的空腔中。这种独特的结构在生长的ACNTs和蚀刻的Al衬底之间产生了很强的结合强度。ACNT/蚀刻铝箔的等效串联电阻和弯曲试验后的变形的最小变化证明了所制备的复合材料的良好的柔性和结构稳定性。这种柔性的、无粘结剂的ACNTs/蚀刻铝箔复合材料具有优异的电化学和散热性能。本工作提供了一种通用的和适应性强的方法，通过形成微尺寸和不规则形状的腔在不同类型的衬底上生长具有强剥离强度的碳纳米管，为各种实际应用。
In this work, aligned carbon nanotubes (ACNTs) were grown on etched Al foil with improved bonding strength by direct thermal chemical vapor deposition. In the interface of the ACNTs adjacent to the etched Al substrate, the ACNTs, tangled together as irregularly shaped “tiny twine balls,” were embedded in the cavities of the etched Al foil. Such a unique structure generated strong bonding strength between the as-grown ACNTs and etched Al substrate. The minimal changes for the equivalent series resistance and deformation of the ACNT/etched Al foil after bending test demonstrated the good flexibility and structural stability of the as-prepared composite material. This flexible, binder-free ACNTs/etched Al foil composite material exhibited excellent electrochemical and thermal dissipation performances. This work provided a versatile and adaptable method by forming micro-sized and irregularly shaped cavities on different kinds of substrates to grow CNTs with strong peel strength for various practical applications.
