Nylon-4,6 nanofibres with diameters ranging from about 1 µm down to nm were prepared by electrospinning. The fibre diameter was varied adjusting the concentration of polymer solution. Electrospinning a concentrated solution as high 20% nylon-4,6 weight in formic acid produced ribbon-like electrospun ribbon width 850 nm. A semi-dilute 2% thinnest 1.6 or less. small amount pyridine added electrospinning avoid formation beaded course at low concentrations. Scanning and transmission electron...
It is challenging to explore a unified solution for the treatment of oily wastewater from complex sources. Thus, membrane materials with flexible separation schemes are highly desired. Herein, we fabricated smart by electrospinning TiO2 doped polyvinylidene fluoride (PVDF) nanofibers. The as-formed beads-on-string structure and hierarchical roughness nanofibers contribute its superwetting/resisting property liquids, which desirable in oil/water separation. Switched simply UV (or sunlight)...

A flexible slippery membrane (FSM) with tunable morphology and high elastic deformability has been developed by infusing perfluoropolyether (PFPE) into a fluorinated-copolymer-modified thermoplastic polyurethane (TPU) nanofiberous membrane. To immobilize PFPE in TPU matrix, we synthesized fluorinated-copolymer poly(DFMA-co-IBOA-co-LMA) low surface energy, chemical affinity to PFPE, adequate flexibility, strong physical adhesion on TPU. Upon external tensile stress, the as-prepared FSM can...
