Electrically conductive nanofiber is well known as an excellent nanostructured material for its outstanding performances. In this work, poly(3,4-ethylenedioxythiophene) (PEDOT)-coated polyvinyl alcohol-graphene oxide (PVA-GO)-conducting nanofibers were fabricated via a combined method using electrospinning and electropolymerization techniques. During electrospinning, the concentration of PVA-GO...

Electrospinning is based on so-called bending instability which results in an erratic spiralling motion of the liquid jet as it proceeds towards a collecting electrode, where it is eventually deposited as a mat of micro/nanosized fibres. Most electrospinning models formulated within the slender approximation rely, however, on an inconsistent description of electrostatic interactions which rende...

Abstract The mass electrospinning is the key way to promote industrial application of nanofibrous membrane, in which multi-parameter controlling challenge for multi-needle electrospinning. A constant temperature and humidity environment was introduced studied effect process parameters on ejection process. This article focused nanofiber deposition behaviors from two different polymer solution aq...

The one-dimensional (1D) mesoporous and interconnected nanoparticles (NPs) enriched composite Co3O4-CuO nanofibers (NFs) in the ratio Co:Cu = 1/4 (Co3O4-CuO NFs) composite have been synthesized by electrospinning and calcination of mixed polymeric template. Not merely the mesoporous composite Co3O4-CuO NFs but also single mesoporous Co3O4 NFs and CuO NFs have been produced for comparison. The c...

Electrospinning of nanomaterial composites are gaining increased interest in the fabrication of electronic components and devices. Performance improvement of electrospun components results from the unique properties associated with nanometer-scaled features, high specific surface areas, and light-weight designs. Electrospun nanofiber membrane-containing polymer electrolytes show improved ionic ...

Dye Sensitized solar cell (DSSC) have been looked upon as having the potential to modernize photovoltaic as a cost effective technology. Especially nanostructured DSSC is proposed to have the capability to boost the efficiency by limiting charge recombination, thereby increasing the charge transportation which affects the overall conversion efficiency favourably. In the present work we discuss ...

Electrospun nanofiber scaffolds have been shown to accelerate the maturation, improve the growth, and direct the migration of cells in vitro. Electrospinning is a process in which a charged polymer jet is collected on a grounded collector; a rapidly rotating collector results in aligned nanofibers while stationary collectors result in randomly oriented fiber mats. The polymer jet is formed when...
