A thin film of a new type of carbon nanostructures is synthesised, by plasma enhanced chemical vapour deposition. Individual nanostructure has a multi-walled carbon nanotube aligned perpendicular to the surface of the substrate, with carbon films attached to the nanotube like branches, giving it a tree like appearance. Raman spectroscopy confirmed that the material is overall graphitic in nature. Different deposition parameters are varied to understand the growth mechanism of the nanostructures and the factors affecting its morphology. It is understood that in a condition where a higher content of carbon is present in the plasma than for the condition in which aligned carbon nanotubes are formed, the formation of the branches on the carbon nanotubes takes place, resulting in the tree like nanostructures. The material can be deposited in different substrates irrespective of the roughness, the conductivity or the nature of the substrate and exhibits superhydrophobicity. This novel carbon nanostructured thin film with a very high exposed surface area has a potential of application in all fields which require high surface area, structured or superhydrophobic material.

垂直排列和树状碳纳米结构的合成

通过等离子体增强化学气相沉积合成了一种新型碳纳米结构的薄膜。单个纳米结构具有垂直于基板表面排列的多壁碳纳米管，碳膜像树枝一样附着在纳米管上，使其外观像树一样。拉曼光谱证实该材料本质上是整体石墨。不同的沉积参数是不同的，以了解纳米结构的生长机制和影响其形态的因素。应当理解，在等离子体中存在比形成排列的碳纳米管的条件更高的碳含量的条件下，发生在碳纳米管上的分支的形成，导致树状纳米结构。无论基材的粗糙度、导电性或性质如何，该材料都可以沉积在不同的基材中，并表现出超疏水性。这种具有非常高暴露表面积的新型碳纳米结构薄膜具有在需要高表面积、结构化或超疏水材料的所有领域中的应用潜力。(C) 2018 Elsevier Ltd。保留所有权利。
