Abstract:
A superamphiphobic (SAP) surface was fabricated by electrodepositing Cu-Ni micro-nano particles on aluminum (Al) substrate and modifying via 1H,1H,2H,2H-Perfluorodecyltrimethoxysilane (FAS-17). 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° and oil contact angle of 151.6°. The mechanical strength and chemical stability of the SAP surface were tested further. The experimental results showed that the SAP surface present excellent resistance to wear, prominent acid-resistance and alkali-resistance, self-cleaning and anti-fouling properties.
