Electrospinning is considered one of the most efficient techniques used for producing fibers in the nanometer to micrometer ranges. The mechanical properties of the electrospun fibers depend on the solution used to produce them. The present study focuses on dissolving the PolyMethalylmethacrylate (PMMA) in acetone solvent. A concentration of 23% PMMA was found to be the best concentration for producing smooth fibers with almost no beads. We studied the effect of mixing the PMMA with two types of nanotubes on the mechanical properties of the fibers. A Carbon-Nano-Tubes (CNT) and Boron-Nitride-Nano-Tubes were mixed with PMMA solution at different ratios to produce a CNT/PMMA and BNNT/PMMA solutions with different concentrations of 0.1%, 0.25%, and 0.6%. Electrospinning technique was used to produce fibers from the PMMA, CNT/PMMA, and BNNT/PMMA solutions. All fibers were tested experimentally with a micro-tensile-tester to produce stress-strain curves that were used to extract the average modulus of elasticity, maximum strength, and fracture point for each fiber. Enhancements in the Youngs modulus and maximum tensile strength of the fibers were observed with the addition of CNTs. Further enhancements were observed with the addition of BNNTs. A random sample of 0.6% CNT/PMMA fibers was tested with Raman spectrometer and the results show a linear change in the frequency-strain curve.
