Lignin-based electrospun nanofibers reinforced with cellulose nanocrystals.
Lignin-based fibers were produced by electrospinning aqueous dispersions of lignin, poly(vinyl alcohol) (PVA), and cellulose nanocrystals (CNCs). Defect-free nanofibers with up to 90 wt % lignin and 15% CNCs were achieved. The properties of the aqueous dispersions, including viscosity, electrical conductivity, and surface tension, were examined and correlated to the electrospinnability and resu...
متن کاملA catechol biosensor based on electrospun carbon nanofibers
Carbon nanofibers (CNFs) were prepared by combining electrospinning with a high-temperature carbonization technique. And a polyphenol biosensor was fabricated by blending the obtained CNFs with laccase and Nafion. Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscope (FE-SEM) were, respectively, employed to investigate the structures ...
متن کاملInterfacial properties of lignin-based electrospun nanofibers and films reinforced with cellulose nanocrystals.
Sub-100 nm resolution local thermal analysis, X-ray photoelectron spectroscopy (XPS), and water contact angle (WCA) measurements were used to relate surface polymer distribution with the composition of electrospun fiber mats and spin coated films obtained from aqueous dispersions of lignin, polyvinyl alcohol (PVA), and cellulose nanocrystal (CNC). Defect-free lignin/PVA fibers were produced wit...
متن کاملGas Sensors Based on Electrospun Nanofibers
Nanofibers fabricated via electrospinning have specific surface approximately one to two orders of the magnitude larger than flat films, making them excellent candidates for potential applications in sensors. This review is an attempt to give an overview on gas sensors using electrospun nanofibers comprising polyelectrolytes, conducting polymer composites, and semiconductors based on various se...
متن کاملSelf assembly and correlated properties of electrospun carbon nanofibers
An investigation of the influence of droplet size conditions and monomer choice on electrospun carbon nanofiber properties is presented. Monomer choices included poly (ε-caprolactone) and poly (methyl methacrylate) with and without the addition of single walled carbon nanotubes. A key property under investigation is the effect of electrospinning conditions on the resulting carbon nanofiber elas...
