Statistical analysis of nanofibers alignment in magnetic‐field‐assisted electrospinning including an alignment percentage formula

Abstract

Magnetic‐field‐assisted electrospinning (MFAES) is a simple and effective method to align polymer nanofibers. In this method, further research is needed to identify alignment mechanism. Hence, this article includes statistical analysis of affecting factors to investigate alignment mechanism in MFAES. Tip to target distance, magnets distance, voltage, and collection time, which are recognized as the most effective factors on nanofibers alignment, were applied in design of experiments. Central composite method was applied to get required experiments with designed expert 8 software. A response surface was proposed with regression coefficient of 97%. Then, the common physics concepts and statistical results were used to discuss the affecting mechanism of the electric and magnetic fields on the electrospinnig jet and the nanofibers alignment. Field emission scanning electron microscopy images were used to characterize the nanofibers alignment and calculate overall alignment percentage using a proposed statistical combinatorial weighted percentage formula. MFAES method, used in this research, achieved 95.3% polyacrylonitrile‐aligned nanofibers. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 41179.

Highly aligned magnetic composite nanofibers fabricated by magnetic-field-assisted electrospinning PAN/FeCo solution

“…19 Among the synthesis methods of ordered nanofibers, 20 –23 the magnetic-field-assisted electrospinning (MFAES) method has been widely employed due to the advantages of simple equipment, easy handling, large production, and so on. 24 –29 However, there have been few reports examining the preparation of aligned magnetic nanofibers using the MFAES method.…”

Magnetic Nanofibers: Unique Properties, Fabrication Techniques, and Emerging Applications

“…Magnetic field assisted method is a method that can improves the performance and controls of the phase morphology of the sample by applying an external magnetic field during preparation. [52] Ordinary electromagnetic process usually use electromagnetic stirring or an electromagnetic brake. However, the magnetic field assisted process inserts high-intensity magnetization energy into the sample, which then changes the thermodynamic state of the sample, resulting in the migration and rearrangement of atoms and molecules.…”

Investigation of Effect of Electrospinning Parameters on the Morphology of Polyacrylonitrile/Polymethylmethacrylate Nanofibers: A Box–Behnken-Based Study

“…[1,3,[18][19][20][21] The morphological structure and dimensions of electrospun fibers are influenced by three types of parameters: material, processing and ambient ones. Polymer type and its molecular weight, polymer concentration, solvent and polymer solution properties (viscosity, conductivity and surface tension) are some of the important material properties.…”
