超疏水叠杯状碳纳米管薄膜的制备
Growth of a cup-stacked carbon nanotube carpet with a superhydrophobic surface
摘要
Abstract
A carpet structure composed of high purity cup-stacked carbon nanotubes (CSCNTs) was synthesized by a catalytic chemical vapor deposition method.In a 15-min growth time,the CSCNT carpet with a height up to ～300 μm and carbon purity above 99.9 mass％ was prepared.Transmission electron microscopy observations indicated that the CSCNTs with diameters ranging from 80 nm to 230 nm consist of truncated conical graphene layers.Based on the experimental results,a possible "base growth"mechanism was proposed for the CSCNTs.The CSCNT carpet is highly flexible and superhydrophobic,showing a contact angle of ～ 155°.It can be easily harvested from the original growth substrate and be transferred to target substrates.It may therefore find applications as a water-proof and self-cleaning coating layer.关键词
