Electrospinning of cellulose nanofiber and poly(vinyl alcohol) blend: experiment and simulation

摘要

This paper reports an electrospinning of cellulose nanofiber (CNF) and poly(vinyl alcohol) (PVA) blend for fabricatingnanocellulose based long filament in terms of experiment and simulation. To enhance spinnability, Triton X-100 anddimethyl sulfoxide (DMSO) was introduced as a surfactant and cosolvent, respectively. Parameters governing theelectrospinning of CNF-PVA blend are voltage, spinning speed, nozzle diameter, the distance between the electrodes,and the viscosity of the blend.Node-based analysis of the electrospinning is performed with electrostatic field modeling via MATLAB software. Withthe simulation results, proper combinations of parameters are determined for CNF-PVA electrospinning. Furthermore,empirical demonstration of the CNF-PVA electrospinning is achieved. Electospun nanofiber mat is investigated by fieldemission scanning electron microscopy.
