Abstract: As an alternative to polymer membranes, ultrathin free-standing single-walled carbon-nanotube network films are used to realize oil/water separation with ultrahigh flux. The films with tunable thickness of the tens of nanometer scale can effectively separate both micrometer and nanometer-sized surfactant-free and surfactant-stabilized water-in-oil emulsions with a flux 2-3 orders of magnitude higher than commercial filtration membranes with similar separation performance.

“…113,114 However, such a structure is difficult to and advanced nanotechnologies provides a new future to revolutionarily improve the membrane performance, especially the flux. [113][114][115][116][117] One-dimensional nanomaterials, such as carbon Advanced membranes for emulsified oil/water separation Y Zhu et al nanotubes, nanowires and nanofibers, are most attractive for constructing fibrous films. 115,116,[118][119][120][121][122] Because of their small diameter, a membrane composed of these structures can possess both an adjustable effective pore size and an ultrathin active separation layer on the nanometer scale.…”

“…Those materials that have not only one kind of superwettability, SHBOI or UWSOB, or without any superwettability, with excellent potential applicability to separate wateroil emulsions will be summarized in this section. Jin's group 51 reported an alternative to polymer membranes based on ultrathin SWCNT network films for the ultrafast separation of emulsified oilwater mixtures. The fabrication of SWCNT network film was similar to the previous example by first vacuum-filtering an SWCNT suspension through an MCE filter membrane and then releasing it from the filter.…”

“…Permeation theory predicts that the filtration rate is directly proportional to the square of the effective pore size of the membrane and inversely proportional to the thickness of the membrane. 51 That is why scientists have been working on trying to prepare thinner membrane with optimal pore size. In fact, a large number of parameters are decisive for emulsion separation: filter properties (surface wettability and roughness, pore size, fiber fineness, permeability, and thickness), dispersed-and continuous-phase properties (droplet size, density difference between phases, interfacial tension, viscosity, and presence of surfactants), and operating conditions (filter and flow orientation, inflow velocity, pressure drop, temperature, and emulsion concentration).…”
