“…The development of superhydrophobic membrane for oilwater emulsions separation was reported [112][113][114][115][127][128][129][130][131][132][133][134][135] as summarized in Table 6. However, there is no publication which clearly states the application of superhydrophobic membrane for waste lube oil processing.…”

Waste lube oils are classified as hazardous waste due to the metal contents derived from the additives and wear. Most lube oils contain up to 20% of additives including antioxidants, anti‐wear, and de‐foaming agents which are generally used to extend the usage of lube oils and enhance engines performance. The most widely‐used additives contain metal as they exhibit efficacy in performance enhancement. However, these additives increase the hazardous level of waste lube oils and are highly toxic when released into the environment. Waste lube oils processing can minimize the toxicity and the complexity of the waste and may produce valuable products at the same time, such as, fuels, solvent, and base oils for production of new lube oils. In this paper, the common technologies for waste lube oils processing, including physical and chemical processes are reviewed. In addition, more recently developed technology such as membrane technologies and their potential application in waste lube oil processing are also discussed. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1867–1881, 2018

“…For oil/water separation, the membrane materials need to possess selective wettability (hydrophilic-oleophobic or hydrophobic-oleophilic). 6,7 For water-in-oil emulsion separation, membranes are fabricated by using hydrophobic-oleophilic materials, such as poly(tetrauoroethylene) (PTFE), 8 poly(vinylidene uoride) (PVDF), 9,10 poly(ethylene chlorotriuoroethylene) (ECTFE), 11 polypropylene (PP), 12 etc. Recently, an emerging uoro-copolymer, PVDF-HFP has been attracting more and more attention.…”

“…The C 1s spectra ( Fig. 3c) exhibit six different peaks at the binding energies of 294.1 ev, 291.6 ev, 289.6 ev, 288.8 ev, 285.5 ev, 283.8 ev, which were respectively assigned to the bonds [22][23][24] the -CF 3 , -CF 2 , -CH 2 -CF 2 came from PFDS. Owing to the low surface energy -CF 3 and -CF 2 components, the anodic Al 2 O 3 layer modified with PFDS is strongly water repellent, as also confirmed in later experiments (CA).…”

Material corrosion induced by temperature variations is one of the main threats to materials immersed in complex and changeable marine environments. Superhydrophobic surfaces (SHS) are promising for protecting the underlying metal from corrosion. However, temperature variations in underwater environments have hindered the practical application of SHS, thus, their corrosion protection ability is limited. However, slippery liquid infused porous surfaces (SLIPS) can compensate for the aforementioned defects of SHS. In this research, a kind of SLIPS was designed over aluminum for marine corrosion applications using a three-step procedure, consisting of anodization, fluorination and solvent exchange method. The as-prepared SHS and SLIPS were characterized with scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and wettability measurement, and their corrosion properties were investigated by electrochemical impedance spectroscopy (EIS). With the perfluorinated lubricant and aluminium oxide coating, the SLIPS presented high corrosion resistance (2.06 × 10 9 Ω cm 2) in a broad temperature range.
