制备可广泛应用的超疏水表面的新方法
首发时间:2012-03-29
摘要:本文报道了一种在实际中可广泛应用的超疏水表面制备新方法。采用涂刷在基体表面得到聚糠醇/铜(PFA / Cu)涂层,并浸入到硬脂酸乙醇溶液中,从而在基体表面生成硬脂酸铜超疏水表面,并利用场发射扫描电子显微镜(FESEM),傅里叶变换红外光谱(FTIR),X射线粉末衍射(XRD),X射线光电子能谱(XPS)对其进行了表征。通过此方法,原来只能在铜基表面生成的超疏水表面也可以在不含铜元素的基体表面上形成。此项研究工作将为在不同基体表面大尺寸制备超疏水表面提供一种简单、通用的方法。

A novel fabrication of superhydrophobic surfaces for universal applicability
Abstract:The present work reports a novel and facile approach to fabricate stable superhydrophobic surfaces for universal applicability in practice. Poly(furfuryl alcohol) / copper composite coatings were prepared on substrates via a brush-painting method; after being immersed in a stearic acid solution, the superhydrophobic surfaces were obtained due to the formation of copper stearate on the substrates. These products were characterized by field-emission scanning electron microscopy, Fourier transform infrared spectrometry, X-ray powder diffraction and the X-ray photoelectron spectrum. Results demonstrate that the superhydrophobic surfaces formed originally on copper substrates can also be generated on other substrates without the copper element. Furthermore, this work will provide a simple and universal method to create large-scale superhydrophobic surfaces on various substrates.
Keywords: superhydrophobic surface copper stearate brush-painting method Poly(furfuryl alcohol) micro / nanostructured hierarchical surface
