Effect of benzyl triethylammonium chloride on microstructure of bicomponent polymeric fibers during electrospinning

Abstract

Effect of benzyl triethylammonium chloride (BTEAC) on the microstructure of electrospun bicomponent fibers, i.e., polyvinylidene fluoride (PVDF)/polycarbonate (PC), polyacrylonitrile (PAN)/polyethylene glycol (PEG), and PAN/PVDF, was investigated in this article. The evolution of morphology and microstructure of the above bicomponent fibers were examined by scanning electron microscopy, transmission electron microscopy, and X‐ray photoelectron spectroscopy. The results showed that distinct core/shell structured fibers were successfully prepared from PVDF/PC and PAN/PVDF via introducing a small amount of BTEAC, whereas only cocontinuous structure was detected in the electrospun PAN/PEG fibers. This study could be an example of electrospun multipolymer dispersions influencing by an organic salt, and it could be extended to control the structure of carbon nanofibers via electrospinning.

Materials design towards sport textiles with low-friction and moisture-wicking dual functions

“…This is because the surface energy of PVDF is lower than that of PAN so that PVDF prefers to stay at the surface of the nanofiber, forming the shell. It worth noting that the distinct core-shell morphology was achieved without incorporation of any salts, which is probably because the solvent used was different from that reported in W Lu's work 16 . DMF may evaporate more slowly than DMF/acetone mixtures and hence give more time for phase separation.…”

Bright Light Emission and Waveguiding in Conjugated Polymer Nanofibers Electrospun from Organic Salt Added Solutions

“…Organic salts are often used for improving electrospinnability and nanofibers uniformity, especially with optically inert polymers. 47,[53][54][55] Indeed, this results in a higher charge density and ultimately in higher elongation forces experienced by the jet. The diameter of the obtained electrospun fibers also becomes essentially smaller, 53,54 which is also consistent with models Published in Macromolecules 46:5935-5942, doi: 10.1021/ma400145a (2013).…”

Preparation and characterization of antimicrobial electrospun poly(vinyl alcohol) nanofibers containing benzyl triethylammonium chloride

“…Benzyl triethylammonium chloride (BTEAC) is a one example of QACs [44]. Some researchers have incorporated BTEAC into polymer solution in order to change the electrical conductivity and surface tension of the solution and to increase spinnability during the electrospinning of nanofibers [45][46][47][48][49]. For instance, You et al [50] added BTEAC to a solution of poly(lactic-co-glycolic acid) (PLGA) during electrospinning to obtain various diameters of BTEAC-PLGA nanofibers.…”
