Recent developments in polymeric electrospun nanofibrous membranes for seawater desalination

Studies of Electrospun Cellulose Acetate Nanofibrous Membranes

The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...

Electrospun membranes: Next generation membranes for desalination and water/wastewater treatment

Fabrication of Electrospun Nanofibrous Membranes for Membrane Distillation Application

Nanofibrous membranes of matrimide were successfully fabricated using electrospinning technique under optimized conditions. Nanofibrous membranes were found to be highly hydrophobic with high water contact angle of 130°. FESEM and pore size distribution analysis revealed the big pore size structure of electrospun membranes even greater than 2μm and the pore size distribution is found to be narr...

Electrospun Nanofibrous Membranes for Highly Sensitive Optical Sensors

The first use of electrospun nanofibrous membranes as highly responsive fluorescence quenching-based optical sensors for metal ions (Fe3+ and Hg2+) and 2,4-dinitrotoluene (DNT) is reported. A fluorescent polymer, poly(acrylic acid)−poly(pyrene methanol) (PAA−PM), was used as a sensing material. Optical chemical sensors were fabricated by electrospinning PAA−PM and thermally cross-linkable polyu...
