Senthil, T.George, G.Anandhan, S.2026-02-052013Polymer - Plastics Technology and Engineering, 2013, 52, 4, pp. 407-4213602559https://doi.org/10.1080/03602559.2012.755546https://idr.nitk.ac.in/handle/123456789/26819The effects of solution and processing parameters on the morphology and diameter of electrospun poly(styrene-co-acrylonitrile) fibers were investigated by design of experiment. Morphology of the electrospun fiber mats were investigated by scanning electron microscopy. With increasing solution concentration, fiber morphology changed from that of a spindle-like beaded one to smooth, and the average fiber diameter increased from 96 to 876 nm. Average fiber diameter gradually increased with applied voltage; however, fiber morphology was only slightly influenced by flow rate. Regression analysis results reveal that solution concentration has the most significant impact on the average and standard deviation of fiber diameter. © 2013 Copyright Taylor and Francis Group, LLC.Average fiber diametersElectrospun fibersIncreasing solutionsPoly(styrene-co-acrylonitrile)Processing parametersSolution concentrationStandard deviation of fiber diameterUltra-fine fibersFibersMorphologyOptimizationOrganic polymersRegression analysisScanning electron microscopyStyreneElectrospinning
