摘要Here we present our findings of superhydrophilic (SHPL)/superhydrophobic (SHPB) Dianthus caryophyllus-like hierarchical structure for corrosion inhibition and biofouling mitigation through a relatively high-speed hard anodisation (HA) technique. The surface morphologies, chemical compositions were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectrophotometer (FTIR). The static and dynamic behaviors of water droplets and water stream demonstrate the extremely low contact angle of SHPL surface and the low adhesive force of SHPB surface. Electrochemical impedance spectra (EIS) in 3.5 Wt% NaCI solution and settlement experiments in Chlorella vulgaris-inoculated culture medium revealed that the SHPL surface cannot efficiently protect the underlying substrates from corrosion and Chlorella wilgaris cell adhesion, whereas the SHPB surface exhibited noticeable corrosion inhibition and biofouling mitigation. In addition, the synthetic SHPB surface presents good self-cleaning ability to contamination and thermal stability to hot water droplets. We believe that our findings of the anodized SHPL/SHPB Dianthus caryophyllus-onnanowires structure are helpful in understanding the difference between superhydrophilicity and super hydrophobicity, which is beneficial for designing new bio-inspired interfacial materials with superwettability for potential marine applications.
