Novel Handheld Electrospinning Device with Nanofiber Concentrator: Design, Performance and Applications |
In this study, a novel handheld battery-operated electrospinning device equipped with a nanofiber concentrator was developed to enhance target area control during nanofiber deposition. The device manipulates the electric field using the dielectric properties of a polymeric tunnel, enabling precise deposition of nanofibers with specific patterns. Low molecular weight chitosan/poly(vinyl alcohol) (CS/PVA) nanofibers with an average diameter of 65 ± 9 nm were successfully synthesized. Finite Element Analysis (FEA) simulations demonstrated the effectiveness of the nanofiber concentrator in stabilizing the whipping jet, reducing deposition area, and increasing accuracy. |

A comparative fractographic analysis for the effect of polymeric nanofiber reinforcements on the tensile behavior of multi-layered epoxy nanocomposites
This study presents a comparative investigation into the effects of four different nanofibers—PA66, PStX, PAN, and PVB—on the mechanical performance and failure mechanisms of epoxy adhesive films. These nanofiber‐reinforced adhesive layers were manufactured via a dry‐reinforcement resin film infusion method and tested under uniaxial tensile loading. Mechanical results showed that PA66 and PStX nanofibers improved tensile strength by up to 25%, primarily by mitigating crack initiation at free edges and promoting effective fiber–matrix bonding. In contrast, PAN nanofibers induced micro‐cracks at the fiber–resin interface, amplifying crack coalescence and reducing strength by 25%. 03/01/2025
