摘要:
将Cu-Ni微纳米颗粒电沉积在铝基底上,通过1H、1H、2H、2H-全氟癸基三甲氧基硅烷(FAS-17)对其进行修饰,制备了超双疏(SAP)表面. 采用扫描电子显微镜、X射线衍射、能量色散X射线光谱和傅里叶变换红外光谱对其形貌和化学成分进行了研究. 结果表明,SAP表面具有三维微纳结构,最大水接触角160.0°,油接触角151.6°. 进一步测试了SAP表面的机械强度和化学稳定性,结果显示该SAP表面具有优良的耐磨性、耐酸耐碱性能、自洁性和防污性能.

Abstract:
A superamphiphobic (SAP) surface was fabricated by electrodepositing Cu-Ni micro-nano particles on aluminum substrate and modifying via 1H,1H,2H,2H-perfluorodecyltrimethoxysilane. Scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and Fourier-transform infrared spectroscopy were employed to investigate the morphology and chemical composition. The results showed that the SAP surface had three-dimensional micro-nano structures and exhibited a maximum water contact angle of 160.0°, oil contact angle of 151.6°, a minimum water slide angle of 0°and oil slide angle of 9°. The mechanical strength and chemical stability of the SAP surface were tested further. The experimental results showed that the SAP surface presented excellent resistance to wear, prominent acid-resistance and alkali-resistance, self-cleaning and anti-fouling properties.
