“…The resulting material is easy to manufacture and efficient in the separation of mixtures of oil and hard water. [64] The aim of this work was to synthesize high performance superhydrophobic/oleophilic membrane. In order to do this, it was vital to fixate SiO 2 nanoparticles on an anodized metallic mesh.…”

Many new achievement developments for different industries have their origin in the basic science. Within the last years, this trend is gaining much attention since the interaction between both fields (scientific and industry) is increasing. This article presents some rational materials chemical modifications that were developed by the basic science and were, then, transferred to the productive sector. Conducting hydrophobic coatings for aerospace applications, hydrogels for the oil & gas industry as well as polymers for removal of heavy metal were some of the topics approached in the lab to solve industrial problems. Many times, nature is a great source of inspiration to produce new materials. In this sense, superhydrophobicity and superhydrophilicity (concepts closely related to our everyday life) were the bioinspiration for the development of membranes. These membranes were able to separate hydrocarbons and water, which found application in the treatment of subterranean water for oil & gas industry.

“…Sosa et al [ 32 ] described a facile one-step scalable method to fabricate mechanically and chemically stable SH coatings on metal meshes ( Figure 11 A–E) for oil–water separation. The process consisted of coating inorganic hydrophilic SiO 2 nanoparticles (to provide nano-scale roughness) and two hydrophobic polymers (PDMS and PVDF) in toluene, followed by curing at 200 °C for 2 h. The fabricated membranes provided a WCA of 158 ± 6°, SA of 3 ± 2°, and a stable oil flux on the order of about 10 2 Lm −2 s −1 .…”

Nature has proven to be a valuable resource in inspiring the development of novel technologies. The field of biomimetics emerged centuries ago as scientists sought to understand the fundamental science behind the extraordinary properties of organisms in nature and applied the new science to mimic a desired property using various materials. Through evolution, living organisms have developed specialized surface coatings and chemistries with extraordinary properties such as the superhydrophobicity, which has been exploited to maintain structural integrity and for survival in harsh environments. The Lotus leaf is one of many examples which has inspired the fabrication of superhydrophobic surfaces. In this review, the fundamental science, supported by rigorous derivations from a thermodynamic perspective, is presented to explain the origin of superhydrophobicity. Based on theory, the interplay between surface morphology and chemistry is shown to influence surface wetting properties of materials. Various fabrication techniques to create superhydrophobic surfaces are also presented along with the corresponding advantages and/or disadvantages. Recent advances in the characterization techniques used to quantify the superhydrophobicity of surfaces is presented with respect to accuracy and sensitivity of the measurements. Challenges associated with the fabrication and characterization of superhydrophobic surfaces are also discussed.

“…In recent years, some newly developed hydrophobic materials have been used for oilwater separation due to the special selectivity toward oil and water. Many materials such as metal meshes, 16 membranes, 17 sponges, 18 and fabrics 19 can be modified into highly hydrophobic or super-hydrophobic as matrix materials to separate oil and water. For example, Liu et al 20 fabricated a durable super-hydrophobic stainlesssteel mesh using a facile solution immersion method.…”

Polymer or polymer gels have been widely used to control excessive water during oil production by homogenizing injection profile and reducing water cut in the produced fluids. However, the gels used are generally unable to selectively minimize water production, and face the challenge of syneresis of gels under high temperature and high salinity environment. In this work, melamineformaldehyde sponge was modified with AlCl 3 solution, rendering a transition from hydrophilic to hydrophobic state with a water contact angle of 130 on the surface of the modified product. Filtration results show that mineral oil and water can be selectively separated with the hydrophobically modified sponge powders. Simulated water shutoff experiments demonstrated the blockage efficiency against water was 30% higher than that against oil, and the oil production was increased 7.4% after blocking. The parallel profile control tests confirmed that the fraction flow of high permeable channel decreased about 75%, accompanied with 60% rise of oil recovery factor. These results indicated that such hydrophobic materials can significantly reduce excessive water production, and this work provided a new idea to offer a low-cost hydrophobic material for conformance control and water shutoff during oil production.
