“…Response surface methodology (RSM) is the most popular method used to model and optimize electrospun nanofibers in recent years . In this work, three main factors of electrospinning (i.e., solution concentration, applied voltage, and tip to collector distance) were investigated to find out the effects of processing parameters on the morphology and membrane structure of electrospun SPEEK nanofibers collected at the constant take‐up speed of 7 m/s.…”

The morphological control of proton conductive nanofibrous mat used in proton exchange membranes (PEMs) is a key issue to improve proton conductivity of PEMs. In this study, response surface methodology (RSM) was utilized to investigate the morphological characterizations of electrospun sulfonated poly(ether ether ketone) (SPEEK) nanofibrous membranes. The effects of electrospinning parameters namely solution concentration, applied voltage and tip to collector distance were studied on the average diameter, its standard deviation and the degree of alignment of SPEEK nanofibers. The adequacy of the response surface models was verified by the validation experiments. Optimized conditions were obtained to meet the desired status of collecting more uniform and finer nanofibers with improved alignment. After obtaining the significant factors and optimal test level, an additional optimization was conducted at different take-up speeds to fabricate high-grade aligned nanofibers. The resultant nanofibers had the diameter of 107 6 22 nm at the optimum point which was in good agreement with the predicted response values. The highest degree of alignment was yielded at the take-up speed of 8.8 m/s with the maximum second-order orientation parameter of 0.869. Electrochemical spectroscopy analysis showed that the aligning of proton conductive nanofibers improved inplane proton conductivity about 67%. POLYM. ENG. SCI., 58:619-631,

In this study and for the first time, aligned nanofibers were produced from low molecular weight polyvinyl butyral. Using response surface methodology, the preparation condition of aligned nanofiber was optimized in terms of nanofiber diameter and its structural stability. Central composite design as a response surface methodology was employed and the effects of process variables and their influence on nanofiber diameter were investigated. Based on a statistical analysis, the use of a model, which was used to determine the nanofiber diameter, proved to be successful because of its low probability value (0.0073) and high correlation coefficient (0.9619). A high-speed cylinder collector was used to fabricate aligned polyvinyl butyral nanofibers. The optimum conditions of 17.5 kV voltage, 10 cm collector distance, 13% solution concentration, and 2100 r/min rotational speed were obtained from experiments. The least diameter of 158.6 nm along with a stable structure was determined for polyvinyl butyral nanofiber prepared under the optimum conditions. An aligned polyvinyl butyral nanoweb was applied on the mid-layer of glass-phenolic laminated composites as an interlaminar reinforcement. The fracture behavior of the laminates was determined by end-notched flexure tests. Excellent toughening property which was observed for the aligned polyvinyl butyral nanofibers caused the mode-II fracture toughness and its maximum force to increase by 25.2 and 40.8%, respectively.

In this work, different sol solutions with various titanium tetraisopropoxide (TIP)/glacial acetic acid ratios in 2‐propanol with 5 wt % poly(vinyl pyrrolidone) (PVP) (Mw = 360,000 g/mol) were prepared and electrospun. Composition of the prepared sols and as‐spun TiO2/PVP nanofibers were determined by Fourier transform infrared and Raman spectroscopy methods. Morphology of the electrospun TiO2/PVP nanofibers was studied by scanning electron microscopy and transmission electron microscopy (TEM) techniques. Rheometry measurements of the sol solutions showed decrease of viscosity upon the addition of TIP to the polymer solutions with constant polymer and acid concentrations. The sol solution having the lowest viscosity (at shear rate 10 s−1) but the highest TIP/glacial acetic acid ratio showed beaded nanofibers morphology when electrospun under 10 and 12 kV applied voltage while injection rate, needle tip to collector distance, and needle gauge were kept constant. However, smooth electrospun TiO2/PVP composite nanofibers with the average nanofibers diameters (148 ± 79 nm) were achieved under the same condition when applied voltage increased to 15 kV. TEM micrographs of the electrospun TiO2/PVP nanofiber showed that the TiO2 particles with continuous structure are formed at the middle of the nanofiber and distributed along its axis. © 2018 Wiley Periodicals, Inc.
