“…Electrospinning, a versatile and widely studied technique, holds significant promise in the fabrication of nanofibrous materials with diverse applications ranging from biomedical engineering to environmental remediation [ 11 , 12 , 13 , 14 , 15 ] due to their favorable properties, low cost, and facile production [ 16 , 17 ]. At the center of this process lies the intricate interplay between the rheological properties of polymer solutions and the resultant fiber morphology [ 18 ].…”

Composite membranes based on a polymer mixture solution of quaternized polysulfone (PSFQ), cellulose acetate phthalate (CAP), and polyvinylidene fluoride (PVDF) for biomedical applications were successfully obtained through the electrospinning technique. To ensure the polysulfone membranes’ functionality in targeted applications, the selection of electrospinning conditions was essential. Moreover, understanding the geometric characteristics and morphology of fibrous membranes is crucial in designing them to meet the performance standards necessary for future biomedical applications. Thus, the viscosity of the solutions used in the electrospinning process was determined, and the morphology of the electrospun membranes was examined using scanning electron microscopy (SEM). Investigations on the surfaces of electrospun membranes based on water vapor sorption data have demonstrated that their surface properties dictate their biological ability more than their specific surfaces. Furthermore, in order to understand the different macromolecular rearrangements of membrane structures caused by physical interactions between the polymeric chains as well as by the orientation of functional groups during the electrospinning process, Fourier transform infrared (FTIR) spectroscopy was used. The applicability of composite membranes in the biomedical field was established by bacterial adhesion testing on the surface of electrospun membranes using Escherichia coli and Staphylococcus aureus microorganisms. The biological experiments conducted establish a foundation for future applications of these membranes and validate their effectiveness in specific fields.

“…Electrospinning is a technique widely used for processing carbon nanotubes and their corresponding polymeric nanocomposites [ 1 , 2 ]. The main benefit of this approach is the possibility to control the fiber diameter and pore size via modifying the setup parameters [ 3 ]. However, this technique cannot be applied to some composites due to their solution viscosity or low conductivity [ 4 , 5 , 6 ].…”

This study focuses on developing hybrid scaffolds incorporating phytotherapeutic agents via a combination of three‐dimensional (3D) printing and electrospinning to enhance mechanical properties and provide antibacterial activity, in order to address the limitations of traditional antibiotics. In this regard, 3D‐printed polycaprolactone (PCL) struts are first fabricated using fused deposition modeling (FDM). Then, alkaline surface treatment is applied to improve the adhesion of electrospun nanofibers. Finally, peppermint oil (PEP) or clove oil (CLV)‐incorporated PCL‐gelatin (GEL) electrospun nanofibers are collected on top of the 3D‐printed PCL scaffolds by electrospinning. Incorporating PEP or CLV into PCL‐GEL electrospun nanofibers enhances the scaffold's layer detachment and adhesion force. In addition, the DPPH free radical scavenging activity assay indicates that incorporating PEP or CLV improves the antioxidant properties of the scaffolds. Further, antibacterial activity results reveal that PEP or CLV incorporated scaffolds exhibit inhibition against Staphylococcus aureus and Escherichia coli bacteria. Moreover, anti‐inflammatory assays show that scaffolds reduce the concentration of nitric oxide (NO) released from Raw 264.7 macrophage‐like cells. On the other hand, the phytotherapeutic hierarchical scaffolds have no toxic effect on normal human dermal fibroblast (NHDF) cells, and PEP or CLV enhance cell attachment and proliferation. Overall, incorporating natural phytotherapeutic agents into hierarchical scaffolds shows promise for advancing wound healing applications.
