Abstract Conventional polymer membranes suffer from low flux and serious fouling when used for treating emulsified oil/water mixtures. Reported herein is the fabrication of a novel superhydrophilic underwater superoleophobic poly(acrylic acid)‐grafted PVDF filtration membrane using salt‐induced phase‐inversion approach. A hierarchical micro/nanoscale structure constructed on surface endows it with superhydrophilic/underwater property. The separates both surfactant‐free surfactant‐stabilized...
Compressive graphene aerogels were obtained by the one-step reduction and self-assembly of oxide with ethylenediamine then freeze-drying. The hold good compressibility, variable electrical resistance fire-resistance. high porosity a hydrophobic nature, allows to absorb different organic liquids, absorption–squeezing process has been demonstrated for oil collection.
A polyionized hydrogel polymer (sodium polyacrylate-grafted poly(vinylidene fluoride) (PAAS-g-PVDF)) is fabricated via an alkaline-induced phase-inversion process. PAAS-g-PVDF coatings exhibit unprecedented anti-adhesion and self-cleaning properties to crude oils under aqueous environment. PAAS-g-PVDF-coated copper mesh can effectively separate a oil/water mixture with extremely high flux oil rejection driven by gravity, oil-fouling-free for long-term use.
A superhydrophobic cotton fabric is prepared by introducing a commercially available fluorinated acrylate monomer, 1H,1H,2H,2H-nonafluorohexyl-1-acrylate, onto under simultaneous radiation-induced graft polymerization. The shows good laundering durability, whereby the superhydrophobicity well kept after 50 individual accelerated launderings, which equivalent to 250 commercial launderings or domestic launderings.
Abstract Due to highly adhesive property, crude oil is easier adhere on foul filtration membranes. Separation of oil‐in‐water emulsion a continuing tough work. Hydrogels with low‐adhesive superoleophobicity are ideal materials for modifying membranes achieve efficient and antifouling separation emulsion. A key challenge in fabricating the hydrogel modified design an ultrathin layer sufficient anti‐crude‐oil‐fouling ability controllable thickness, thus not blocking micro‐ nanosized membrane...

Three-dimensional (3D) graphene aerogels (GA) show promise for applications in supercapacitors, electrode materials, gas sensors, and oil absorption due to their high porosity, mechanical strength, electrical conductivity. However, the control, actuation, response properties of have not been well studied. In this paper, we synthesized 3D decorated with Fe3O4 nanoparticles (Fe3O4/GA) by self-assembly simultaneous decoration using a modified hydrothermal reduction process. The exhibit up 52%...
Graphene oxide (GO) is an excellent bacteria-killing nanomaterial. In this work, macroscopic applications of promising nanomaterial by fixing GO sheets onto cotton fabrics, which possess strong antibacterial property and great laundering durability, are reported. The GO-based fabrics prepared in three ways: direct adsorption, radiation-induced crosslinking, chemical crosslinking. Antibacterial tests show that all these GO-containing could inactivate 98% bacteria. Most significantly, can...
Herein, we demonstrate that reduction of graphene oxide (GO) could be implemented by γ-ray irradiation in alcohol/water the absence oxygen. The resultant reduced GO (RGO) appears highly and possesses high purity through UV-Vis, XPS, FT-IR spectra elemental analysis. We speculate production reductive radicals from γ-radiolysis solvents is main mechanism for oxygen reducing graphite restructuring sheets. control experiments show alcoholic addition are essential factors process, which...
The exclusive location of compatibilizers at the interface immiscible binary polymer blends to bridge neighboring phases is most important issue for fabricating desirable materials with synergistic properties. However, positional stability remains a challenge in both scientific and technical points view due intrinsic flexibility compatibilizer molecules against aggressive processing conditions. Herein, taking typical poly vinylidene fluoride (PVDF)/polylactic acid (PLLA) blend as an example,...
