Insights into electrospun polymeric nanofiber mats: an innovative dressing for wound healing applications in ssalimpour

In this study, a cryogel/nanofiber hybrid material was developed using a new lotus-leaf-inspired strategy. The lotus effect was generated via beaded poly( ε -caprolactone) (PCL) nanofibers produced from the 9 wt% PCL solution with low viscosity and high surface tension via electrospinning. A poly(hydroxyethyl methacrylate) (PHEMA) cryogel layer was constructed through polymerization onto the beaded PCL nanofibrous mat. The thickness of the PHEMA cryogel/beaded PCL nanofiber hybrid material was 3.19 ± 0.07 mm. Morphological characterization studies of the hybrid material were conducted by scanning electron microscopy (SEM). The mean diameter of the beaded PCL nanofibers was 97.22 ± 21.18 nm. 2024-03-01

Nanofibers can be produced by various techniques, such as a broad range of electrospinning techniques to produce nanofiber mats from different polymers or polymer blends, often filled with metallic or semiconducting nanoparticles or by different nanotechnological bottom-up or top-down methods. They are important parts of a wide variety of energy applications, such as batteries, fuel cells, photovoltaics, or hydrogen storage materials. Usually, their physical or chemical parameters are measured by averaging over a fiber bundle or a part of a nanofiber mat. Here, we report the possibility of measuring the different physical and chemical properties of single nanofibers and nanowires. 2024-10-01

Purpose As a result of referee evaluation, the subject scope of the article has been expanded. Previously, only polycaprolactone (PCL) loaded with peppermint extract had been studied. As a result of peer review, nanostructure production was made with peppermint-loaded polylactic acid (PLA). Literature information about PLA polymer has been added to the Introduction section. Additionally, to analyze the presence of peppermint extract in Fourier transform infrared (FTIR) measurements, a comparison was made with 100% PCL, 100% PLA and 100% peppermint extract. In order to observe the effect of polymer type, evaluations were made between the produced peppermint-loaded nanostructures containing 2024-12-01

Proc. 2025, 21, 1. Abstract: Carbon nanofiber mats can be applied for diverse energy applications. Usually, they should be freestanding and show sufficient structural stability. Poly(acrylonitrile) (PAN) is often used as the base material for electrospinning due to its high carbon yield during carbonization. Carbonized PAN nanofiber mats, however, may be brittle and break under mechanical load. Here, we report a study of the impact of ZnO and tetraethyl or-thosilicate (TEOS) as nanoparticle additives on the 2025-02-01

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. 2025-02-01
