Multifactorial modeling and optimization of solution and electrospinning parameters to generate superfine polystyrene nanofibers

Abstract

This study was conducted to provide a quantitative understanding of the influence of the different solution and electrospinning variables on the morphology and the mean diameter of electrospun polystyrene nanofibers. In this regard, the effect of different solvents and ionic additives on the electrical conductivity, viscosity, and surface tension of the electrospinning solutions and thereby the morphology of nanofibers were examined. The results indicated that the morphology of the fibers is extremely dependent on the solvent's properties, especially volatility and electrical conductivity, and the ionic characteristics of additives. Finally, to estimate the optimal electrospinning conditions for production of nanofibers with minimum possible diameter, modeling of the process was undertaken using the response surface methodology.Experimentally, nanofibers with the finest diameter of 169 ± 21 nm were obtained under the optimized conditions, and these could be considered promising candidates for a wide practical range of applications ranging from biosensors to filtration.

Encapsulation of rosemary essential oil in zein by electrospinning technique

“…Generally, increasing the level of electrical conductivity in the solution caused enhancements in the charge density of jet. Therefore, higher charges carried by the solution will increase the stretching of the solution which, in turn, will yield fibers with smaller diameters (Nayak et al., 2013; Ramakrishna et al., 2005; Rezaei et al., 2018; Tan et al., 2005).…”

Moisture‐Wicking, Breathable, and Intrinsically Antibacterial Electronic Skin Based on Dual‐Gradient Poly(ionic liquid) Nanofiber Membranes

“…The second gradient is the fiber diameter and pore size of electrospun fiber membranes, which can similarly affect the moisture transportability of fiber membranes. It is determined by the distance between the needle tip and the receiving roller, the spinning fluid concentration, the rotation rate of the roller, the electrostatic voltage, and the extrusion rate, [54][55][56] while the viscosity, electrical conductivity, and surface tension [57][58][59] of the electrospun solution can also affect the process of nanofiber network formation (Figure S6, Supporting Information). Because PIL has high conductivity (see Table S1, Supporting Information) due to the separation of positive and negative charges, the pore size of the PIL nanofiber membrane can be easily controlled.…”

Preparation of PVDF/FMBO composite electrospun nanofiber for effective arsenate removal from water

“…Also, in principle, electrospinning improves removal of organic solvent aer casting, which has environmental implication. [37][38][39] Table 1 presents the composition of dope solutions prepared for synthesizing four different types of electrospun PVDF/FMBO NFs. For electrospinning a mixture was rstly prepared by dissolving PVP as pore former agent in DMF solvent.…”
