“…The solid state 29 Si NMR spectra of the samples were measured to confirm the chemical bond formation by reaction of trichloloro(alkyl)silane with surface hydroxyl groups (silanols) of the silica nanoparticle. The superhydrophobic silica was coated over the PP fabric by the simple dip-coating preparation method.…”

A facile one-step dip-coating method is reported here to prepare recyclable superhydrophobic polypropylene membrane. The membranes with nanoscale surface roughness and contact angle (water) greater than 150° were created by dipping polypropylene fabric film in solution of silica nanoparticles networked with alkylsiloxanes and they exhibited excellent oil flux for oil-water separation under gravity-induced simple separation system. Taking into consideration of its separation selectivity, productivity flux, reusability and endurance, the membrane shows promising in treatment of oily wastewater and oil spill cleanup.

A simple and economical method using graphene oxide for the fabrication of water/oil separation papers

We present a facile method using graphene oxide for the preparation of water/oil separation papers. We coated regular paper with graphene oxide by spraying or soaking, and performed thermal annealing at 180 C for 1-3 hours. The thermal treatment transforms the paper from hydrophilic to hydrophobic due to the thermal reduction of graphene oxide, and thus water can hardly permeate through the separation paper. In contrast, low polarity organic solvents and oil can easily pass through the separation paper. The water/oil separation papers have very good reusable stability. The separation selectivity is above 99% for different mixtures of oily solvents and water.

“…Porous materials have recently attracted significant attention for oil/water separation [14][15][16][17][18][19]. Compared with other porous materials, porous silicones have their own advantages when used to oil/water separation due to low cost, low surface tension and energy, high wetting ability, and good recyclability [20].…”

The separation of oil–water mixtures is increasingly desired due to the environmental protection and industrial production. However, the low‐oil capacity and complicated procedures in current systems remain challenging issues. Herein, porous polydimethysiloxane (PDMS) sponges are fabricated by polymerization of the prepolymer and a curing agent with the combination of NaHCO3 foaming and CO2 template method, which is novel, simple, and economical. EDS and XPS measurements prove the successful fabrication of PDMS sponges. This as‐prepared PDMS sponges show high absorption capacity (694–2513%), hydrophobicity/oleophilicity property (water contact angle and oil contact angle are 139° and 0°), and excellent thermal property. The PDMS sponges can selectively absorb a large amount of floating oils on the water surface and heavy oils under the water, and show little change of its capacities after 20 absorbing/reabsorbing cycles. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S86–S92, 2019
