“…Some researchers believed that an increase in the flow rate resulted in an increased ejected volume leading to the increase in fiber diameter [ 38 ]. Also, the rapid advancement of the spray solution resulted in a rapid increase in fiber diameter due to incomplete drying of the fibrous mats [ 29 , 39 ]. From ( Figure 7 ), we can observe that there is a decrease in fiber diameter on increasing the flow rate of solution from 10μl/min to 15μl/min.…”

Background: Poly lactic-co-glycolic acid (PLGA) has been widely investigated for various biomedical applications, such as craniofacial bone regeneration, wound dressing and tissue engineering. Electrospinning is a versatile technology used to produce micro/nanoscale fibers with large specific surface area and high porosity. Purpose: The aim of the current study is to prepare PLGA nanofibers using electrospinning for guided tissue regeneration/guided bone regeneration applications. The objective of this study is to determine the appropriate electrospinning parameters such as applied voltage, flow rate, spinneret-collector distance and polymer solution concentration for preparation of PLGA fibrous membrane and their effect on the mean fiber diameter of the electrospun fibers. Method: PLGA pellets were dissolved in Hexafluoroisopropanol (HFIP) in various concentrations overnight using a bench rocker. The resulting PLGA solution was then loaded into a syringe and electrospinning was done by maintaining the other parameters constant. Similarly, various fibrous mats were collected by altering the specific electrospinning parameter inputs such as applied voltage, flow rate and spinneret-collector distance. The morphology of the fibrous mats was characterized using Scanning Electron Microscope. The mean fiber diameter was assessed using ImageJ software and the results were compared using one-way ANOVA. Results: We obtained bead-free uniform fibers with various tested solution concentrations. One-way ANOVA analysis demonstrated significant variation in mean fiber diameter of the electrospun fibers with altering applied voltage, solution concentration, flow rate and spinneret-collector distance. Conclusion: The above-mentioned electrospinning parameters and solution concentration influence the mean fiber diameter of electrospun PLGA nanofibers.

“…Even simple syringe pumps have a high degree of control of the flow rate, making them good candidates for electrospinning. Attaching a metal needle to the end of the syringe, and charging (or grounding) the needle fulfils the basic feed requirements for electrospinning and is often as far as researchers need to go for proof-of-concept studies [18][19][20][21][22][23], or basic morphology work [24][25][26][27][28]. An extension of this method is to utilize multiple needles on the same syringe pump to increase the material throughput and the electrospinning footprint on the collector [29][30][31].…”

“…When the voltage is too high, the charge density on the surface of the jet is too large, which easily causes current disorder and jet instability [ 33 ]. Moreover, only within a certain range of feed rates can the stability of the Taylor cone be ensured, as well as the solvent evaporation, molecular chain stretching, and crystallization of the polymer solution jet [ 34 , 35 ]. Finally, with an appropriate spinning distance and spinning voltage, the fiber diameter can be reduced, and the fiber can be fully stretched in the electric field to improve the crystallinity of nanofibers, which is beneficial to enhancing the mechanical properties of nanofibers [ 36 ].…”

This work concentrated on the interlaminar mechanical properties and toughening mechanism of carbon fiber-reinforced bismaleimide resin (CF/BMI) composites modified by polyacrylonitrile (PAN) nanofiber films. The PAN nanofiber films were prepared by electrospinning. End-notched flexure (ENF) and short-beam strength tests were conducted to assess the mode II fracture toughness (GIIc) and interlaminar shear strength (ILSS). The results showed that the GIIc and ILSS of PAN-modified specimens are 1900.4 J/m2 and 93.1 MPa, which was 21.4% and 5.4% higher than that of the virgin specimens (1565.5 J/m2 and 88.3 MPa), respectively. The scanning electron microscopy (SEM) images of the fracture surface revealed that the PAN nanofiber films toughen the composite on two scales. On the mesoscopic scale, the composite laminates modified by PAN formed a resin-rich layer with high strength and toughness, which made the crack propagate across the layers. At the microscopic scale, the crack propagation between two-dimensional nanofiber films led to constant pull-out and breakage of the nanofibers. As a result, the interlaminar fracture toughness of the composite laminates improved.
