Bicomponent nanofibers with piezoelectric and latent-crimp properties were fabricated from two polymer solutions of polyvinylidene fluoride (PVDF) and polyurethane (PU) by electrospinning. Experimental conditions for electrospinning, such as applied voltage, solution concentration, and flow rate, were investigated to determine the optimal conditions for fabricating the bicomponent nanofibers. As a result, 21 wt% solution concentration, 0.5 ml/h flow rate, and 15 kV applied voltage were identified as optimum conditions for electrospinning the bicomponent nanofibers. The morphologies of the side-byside structure of the PVDF/PU fibers were observed. The formation of ${\beta}$-phase crystals by electrospinning was confirmed by Fourier transform infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC). Additionally, it was confirmed that the applied voltage does not have a significant effect on the formation of ${\beta}$-phase crystals. After the hydrothermal treatment, the ${\beta}$-phase crystalline content in the bicomponent fibers remained unchanged.
