|
摘要
改善超疏水表面的普适性、稳定性和耐磨性是超疏水材料实用化的前提。本研究通过水热反应和表面修饰成功制得接触角达156.2°、滚动角为3～4°的铜基超疏水表面。利用接触角测量、扫描电镜观察、XRD测试、红外光谱和EDS分析对超疏水铜表面的润湿性能、表面微结构、相结构和化学结构进行了分析表征。结果表明:所制备的超疏水表面是由大量Cu2S晶粒堆积形成的微纳米二元结构及接枝的疏水长链构成,二者共同赋予铜基超疏水表面广泛的普适性和良好的稳定性。同时,该超疏水表面具有良好的耐磨性和优异的自清洁性能。本工作对此项性能产生的原因和机理进行了分析探讨,以期为超疏水材料在实际生产和生活中的应用奠定基础。
It is a prerequisite that improving the universality,stability,and wear resistance of superhydrophobic materials for the practical applications.In this study,copper-based superhydrophobic surface with a contact angle of 156.2°and a rolling angle of3—4°was prepared successfully by hydrothermal reaction and surface modification.The wettability,surface microstructure,phase structure,and chemical structure of superhydrophobic copper surface were characterized by contact angle measurement,SEM observation,XRD test,FT-IR and EDS analyses.Results showed that the as-prepared superhydrophobic surface was composed of a large number of Cu2 S crystals grafted with long hydrophobic chains,and which lead to the surface presents micro-and nano-scaled binary structure.Consequently,the copper-based superhydrophobic surface was endowed with a wide range of universality and good stability.Meanwhile,the superhydrophobic surface exhibited good wear resistance and excellent self-cleaning performance.These provide a foundation for the practical application of superhydrophobic materials.
