Producing PMMA fibers by electrospinning and model prediction

PMMA fibers were produced by electrospinning from PMMA(poly-methyl-methacrylate)/ethyl acetate solution. Scanning electron microscope(SEM)was used to observe the fibers morphology. The influence of solution concentration, solution flow rate and operating voltage on fiber average diameter was investigated. The Box-Behnken design was used with three main factors, i. e. PMMA solution concentration, solution flow rate and operating voltage. Average diameter of PMMA nanofiber was set as response value. A binary regression model with a high degree of matching the results of experiment was set up by regression analysis. In addition, the results of response surface analysis agreed with univariate analysis results.
