Nanofibrous Membranes

To address the worldwide oil and water separation issue, a novel approach was inspired by natural phenomena to synthesize superhydrophilic and underwater superoleophobic organic/inorganic nanofibrous membranes via a scale up fabrication approach. The synthesized membranes possess a delicate organic core of PVDF-HFP and an inorganic shell of a CuO nanosheet structure, which endows super-flexible properties owing to the merits of PVDF-HFP backbones, and superhydrophilic functions contributed by the extremely rough surface of a CuO nanosheet anchored on flexible PVDF-HFP. Such an organic core and inorganic shell architecture not only functionalizes membrane performance in terms of antifouling, high flux, and low energy consumption, but also extends the lifespan by enhancing its mechanical strength and alkaline resistance to broaden its applicability. The resultant membrane exhibits good oil/water separation efficiency higher than 99.7%, as well as excellent anti-fouling properties for various oil/water mixtures. Considering the intrinsic structural innovation and its integrated advantages, this core–shell nanofibrous membrane is believed to be promising for oil/water separation, and this facile approach is also easy for scaled up manufacturing of functional organic/inorganic nanofibrous membranes with insightful benefits for industrial wastewater treatment, sensors, energy production, and many other related areas.

Controllable Size

ABSTRACTSpherical carbon particles (CPs) with controllable size and surface functionalities were prepared via hydrothermal treatment using sucrose as a precursor and then post modification methods. The CPs were prepared in two steps; firstly, dewatering of sucrose molecules at relatively low temperatures and secondly, carbonization at high temperatures. The micro/nano-sized CPs were functionalized by 2-Acrylamido-2-methylpropane sulfonic acid (AMPS), (3-Acrylamidopropyl)-trimethylammonium chloride (APTMACI), and N-isopropylacrylamide (NIPAM) in order to have the corresponding polymers on the surface of CPs. The monomers were polymerized via atom transfer radical polymerization (ATRP) by means of grafted initiator onto the CPs surface. Additionally, copolymer of these monomers was synthesized to introduce additional properties. The stability of the functionalized CPs in different solutions, and pH, temperature responsive behaviors of the newly prepared CP-polymers composite were evaluated.
