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.

“…In FTIR spectrum of FL-BP/PFDTS (Figure 2e), the peaks observed at ≈1246.3 and ≈1208.2 cm −1 are assigned to asymmetric and symmetric stretching of the -CF 2 -moiety, and the sharp band at 1157.4 cm −1 corresponds to the -CF 2 -CF 3 end group. [30] The covalent bond of SiOSi is supposed to be evolved from hydrogen bonds between a pair of Si-OH groups during PFDTS hydrolysis. [29] These bands are close to those of PFDTS (Figure 2e), indicating the presence of the long-chain fluoroalkyl units on the FL-BP surface.…”

Few‐layer black phosphorus (FL‐BP) has been intensively studied due to its attractive properties and great potential in electronic and optoelectronic applications. However, the intrinsic instability of FL‐BP greatly limits its practical application. In this study, the amphiphobic FL‐BP is achieved by functionalization of 1H,1H,2H,2H‐perfluorooctyltrichlorosilane (PFDTS) on the surface of FL‐BP. The obtained PFDTS coated FL‐BP (FL‐BP/PFDTS) demonstrates enhanced stability, which is not observed during significant degradation for 2 months in high moisture content environment (95% humidity). Particularly, attributing to the surface amphiphobicity, FL‐BP/PFDTS exhibits strong surface water repellency in the presence of oleic acid (as the contaminant), while other passivation coating layers (such as hydrophilic or hydrophobic coating) become hydrophilicity under such conditions. Owing to this advantage, the obtained FL‐BP/PFDTS demonstrates enhanced stability in high moisture content environment for 2 months, even though the surface is contaminated by oil liquid or other organic solvents (such as oleic acid, CH2Cl2, and N‐methyl‐2‐pyrrolidone). The passivation of FL‐BP by amphiphobic coating provides an effective approach for FL‐BP stabilization toward future applications.

“…18 Inspired by natural superhydrophobic living organisms such as lotus leaves and rose petals, increasing attention has been focused on special surface roughness with 3D microand nanostructures, followed by coating a hydrophobic layer to achieve a superhydrophobic surface. 14,[19][20][21] To fabricate such surfaces, various approaches have been employed, including templating, 22 sol-gel processes, 23 chemical vapor deposition, 24,25 electrospinning, 26 anodization, 27 evaporationinduced phase separation, 28 etc. Unfortunately, these reported methods usually suffer from relatively complicated strategies, time-consuming processes, corrosive or poisonous etchants, and expensive equipment that hamper their large-scale applications.…”
