“…Copper were ground with abrasive paper and ultrasonically cleaned in acetone, ethanol and ultrapure water for 10 min, respectively, to remove the grease. Then, the substrates were immersed into 5‐mM HNO 3 with 1.2‐mM CTAB under ultrasonication at room temperature for 20 min to fabricate appropriate roughness structure, followed by rinsing with a great deal of ultrapure water …”

A novel bilayer superhydrophobic film was constructed on Cu substrate by a simple multi-step process. First, (3mercaptopropyl) trimethoxysilane (MPTMS) molecules were self-assembled onto the pre-etched Cu surface via covalent bonding followed by hydrolysis and condensation, then 1H, 1H, 2H, 2H-perfluorodecyltrichlorosilane (PFDTS) were grafted onto the resultant hydroxyl terminated surface via the Si-O-Si bonding. The so-prepared sample was defined as Cu-MPTMS-PFDTS. The structure and morphology of the samples were characterized by means of contact angle measurement, X-ray photoelectron spectroscopy and scanning electron microscopy. The corrosion behaviors of the films were evaluated by Tafel plot and electrochemical impedance spectroscopy on an electrochemical work station. The results indicated that the bilayer superhydrophobic film possessed better corrosion protection as compared with the control samples. The superiority of the corrosion protection was mainly ascribed to the following two aspects: the superhydrophobicity and polysiloxane micro-structures of the Cu-MPTMS-PFDTS.

Oil sorbents play a very important part in the remediation processes of oil spills. To enhance the oil-sorption properties and simplify the oil-recovery process, various advanced oil sorbents and oil-collecting devices based on them have been proposed recently. Here, we firstly discuss the design considerations for the fabrication of oil sorbents and describe recently developed oil sorbents based on modification strategy. Then, recent advances regarding oil sorbents mainly based on carbon materials and swellable oleophilic polymers are also presented. Subsequently, some additional properties are emphasized, which are required by oil sorbents to cope with oil spills under extreme conditions or to facilitate the oil-collection processes. Furthermore, some oil-collection devices based on oil sorbents that have been developed recently are shown. Finally, an outlook and challenges for the next generation of oil-spill-remediation technology based on oil-sorbents materials are given.
