Polysulfone (PSF)/polyacrylonitrile (PAN) membrane had been developed by electrospinning method to investigate the ability of membrane for oil/water separation. The ratios of PSF to PAN were varied as 7:3, 5:5, 3:7, and 0:10 in 10wt% of total concentration. In general, ratio PSF to PAN 5:5 gave the best morphology with smooth nanofibers and good permeability. The results show that increase of PAN concentration leads to the increase of water permeability. The addition of PAN into PSF changed the membrane surface properties from hydrophobic to hydrophilic. PAN/PSF membrane with a ratio of PSF to PAN as 5:5, 3:7, and 0:10 were showing high resistant for oil. It suggested that PSF/PAN membrane with the large composition of PAN could be used as water/oil separator.

Abstract Oily wastewater is an urgent issue threatening the ecosystem and human health. Superhydrophobic porous materials are widely concerned as promising candidates for effective oil/water separation and oil adsorption. However, superhydrophobic porous materials are still confronted with frustrations such as complex preparation processes and secondary pollution to the environment. Superhydrophobic porous materials with biodegradability and a relatively simple preparation process are more attractive to practical application and environmental protection. In this work, biodegradable and industrially applied polylactic acid (PLA)nonwoven materials were used as porous membranes, then PLA nanoparticles were loaded on the membrane surface to construct the hierarchical rough structure. The modified PLA nonwoven membrane (Nano-PLA) shows superhydrophobicity and efficient oil/water separation performance. Moreover, strong mechanical strength and acceptable toughness are obtained. This work offers an easily controlled and industrially used pathway for the design of robust, highly selective, and biodegradable oil/water separation materials.

Surface coating can allow the bulk materials to remain unchanged, while the surface functionality is engineered to afford a more wanted characteristic. Ceramic coatings are considered as ideal coatings on metal which can significantly improve the surface properties of metal materials including anti-fouling, self-cleaning, corrosion resistance, wear resistance, oil/water separation and biocompatibility. Furthermore, various techniques have been utilized to fabricate a range of different ceramic coatings with more desirable properties on metal materials, which make the materials widely used in service environment. This chapter focus will be on the types, fabrication methods, surface properties and applications of ceramics coated metal materials.
