Abstract Although there have been many reports on the preparation and applications of various polymer nanofibers with electrospinning technique, understanding synthetic parameters in remains limited. In this article, we investigate experimentally influence solvents morphology poly(vinyl pyrrolidone) (PVP) micro/nanofibers prepared by PVP solution different solvents, including ethanol, dichloromethane (MC) N , ‐dimethylformamide (DMF). Using 4 wt % solutions, fibers from MC DMF had a shape...
A novel multifunctional microsphere with a fluorescent CdTe quantum dots (QDs) shell and magnetic core (Fe(3)O(4)) has been successfully developed prepared by combination of the hydrothermal method layer-by-layer (LBL) self-assembly technique. The resulting Fe(3)O(4)@C@CdTe core/shell microspheres are utilized as chemosensor for ultrasensitive Cu(2+) ion detection. fluorescence obtained could be quenched effectively ions. quenching mechanism was studied results showed existence both static...
Silver nanoparticles prepared through reduction of AgNO3 by ethanol under refluxing conditions in polyvinyl pyrrolidone (PVP) solution were dispersed into PVP nanofibre film electrospinning. The optical properties Ag measured ultraviolet–visible (UV–vis) spectroscopy. presence face-centred cubic (fcc) crystalline silver embedded was indicated the x-ray diffractometer (XRD) pattern. morphology and distribution nanofibres observed transmission electron microscopy (TEM). interaction between...
Abstract Gold nanoparticles prepared by trisodium citrate reduction of HAuCl 4 in poly(vinylpyrrolidone) (PVP) ethanol solution were dispersed into PVP nanofibers electrospinning. The optical property Au before and after electrospinning was measured UV‐Vis. morphology distribution gold observed transmission electron microscopy (TEM). influence the amount added to concentration over Au/PVP studied. © 2007 Wiley Periodicals, Inc.

Abstract Polyacrylamide (PAAm) with ultrahigh molecular weight of 9 × 10 6 g/mol has been processed by means electrospinning, to afford products a variety morphologies, including polymer colloids, beaded fibers, smooth and ribbons. These morphologies can be controlled minute change solution concentration in small range (0.3–3.0 wt %), because the high polymer. Under our experimental conditions, no electrospun product was obtained at concentrations below 0.3 %. Beaded fibers formed between...
Biodegradable poly(lactide-co-glycolide) (PLGA) antimicrobial nanofibers containing silver nanoparticles were prepared by electrospinning technique. Characterization of the Ag/PLGA nanofiber mats determined using SEM, TEM, WAXD and UV-vis spectrum. The antibacterial efficacy composites made PLGA fibers was measured. antimicroorganization Ag along with biodegradability can be combined in practical medical applications.
A new route based on electrospinning is designed for the preparation of silver chloride/polyacrylonitrile (AgCl/PAN) composite nanofibres. The AgCl nanoparticles uniform in size, were dispersed surfaces Transmission electron microscopy (TEM) images gave direct evidence structure. X-ray photoelectron spectroscopy (XPS) and x-ray diffraction (XRD) confirmed presence crystals.
ABSTRACT Amidoxime‐modified polyacrylonitrile nanofibrous films (AOPAN NFs) were prepared via an electrospinning technique. The traditional preparation methods for amidoximated (AOPAN) solution changed and improved. First, the PAN was modified by hydroxylamine hydrochloride to produce AOPAN solution, then, a small amount of inhibitor added electrospinning. We found that crosslinking inhibited addition inhibitor; at same time, storage time prolonged. In addition, electrospun into films, which...
ABSTRACT Large‐scale superhydrophobic composite films with enhanced tensile properties were prepared by multinozzle conveyor belt electrospinning. First, a strategy of electrospinning was introduced for large‐scale fabrication since the can expand area unlimitedly. During (or electrospraying) process, certain kinds fibers are combined on in one step. The superhydrophobicity electrospun film be achieved presence PS beads and bead‐on‐string PVDF fibers, while submicron PAN responsible...
