Impact of Electro-Magneto Concave Collector on the Characterizations of Electrospun Nanofibers
We introduce a modified approach to produce aligned nanofibers through electro-magneto concave collectors. Both electric and magnetic fields distributions are simulated with COMSOL Multiphysics for different collectors including conventional, concave and modified concave collectors by adding magnetic discs in the back. Orientation matrices are evaluated for each collector in the study, and the highest degree of alignment is found to be with the modified concave collector with a percentage of 68%, followed by the concave collector with a percentage of 57%, which shows an improvement of the proposed method by adding a magnetic field. The generated nanofiber mats from the electro-magneto concave collector show improvements in both mechanical (Young’s modulus = 117.66 MPa) and thermal properties compared to both concave and conventional collectors.
