Abstract

Electrospinning is the most promising process for fabrication of continuos fiber in micron to nano size of diameter with low production cost. However, there are less study on the development of processing window using design of experimental method. Therefore, the main objective of this study is to optimize processing parameters by investigate the effect of electrospinning parameters (Voltage, polymer concentration, and collector rotation speed) on the diameter, orientation, and mechanical properties of fiber. Polymethylmethacrylate (PMMA) which dissolved in solvent (DMF) is spun using self-constructed electrospinning system. Diameter, orientation and physical properties were investigated using Scanning Electron Microscope (SEM). Mechanical properties were measured by tensile test on fibers mat using Universal Tensile Tester with low load cell. Statically analysis on variables parameters based on variation of fiber diameter were done by using Response Surface Method (RSM) from Minitab Software. From Box-Behnken analysis results, the rotation speed and solution concentration are the most significant factors on determination of fibers diameter. Polymer solution concentration and voltage supplied are two significant factors that determine fiber tensile strength. While, collector rotation speed is significant factor in determining the fiber orientation. Optimum parameters to gain lowest diameter, highest Ultimate Tensile Strength (UTS) and fully aligned are distance of 10 cm, voltage of 15kV, pump rate of 5 ml/hr, rotation speed of 450 rpm and PMMA concentration of 10wt%. Accordingly, by applying these values, the lowest diameter that can be obtain is 340 nm, UTS of 1.224MPa, and orientation of 37.04 % aligned. RSM was successfully used to find collaborations between the parameters with the required outputs.
