Oil-spill is one of the major global issues facing society in this century. The aim of this study was to develop a steel-based membrane for selective separation of oil from oil/water mixture. For this purpose, a single-step, rapid and environmentally friendly closed-batch initiated chemical vapor deposition (iCVD) method was employed to deposit hydrophobic thin film on a stainless-steel mesh. Perfluorodecyl acrylate (PFDA) and tert-butyl peroxide (TBPO) were used as monomer and initiator, respectively. Owing to the inherent vapor-based nature of iCVD method provided excellent conformal coverage on the mesh with high durability. iCVD coated mesh showed 96% oil/water separation efficiency. Highly reproducible results were obtained when the oil/water separation experiments were repeated.

A superhydrophobic fluorinated silica functionalized chitosan (F-CS) aerogel is constructed and fabricated by a simple and sustainable method in this study in order to achieve highly efficient gravity-driven oil/water separation performance. The fluorinated silica functionalization invests the pristine hydrophilic chitosan (CS) aerogel with promising superhydrophobicity with a water contact angle of 151.9°. This novel F-CS aerogel possesses three-dimensional structure with high porosity as well as good chemical stability and mechanical compression property. Moreover, it also shows striking self-cleaning performance and great oil adsorption capacity. Most importantly, the as-prepared aerogels exhibits fast and efficient separation of oil/water mixture by the gravity driven process with high separation efficiency. These great performances render the prepared F-CS aerogel a good candidate for oil/water separation in practical industrial application.
