Structural and dielectric properties of electrospun P(VDF-TrFE) and P3HT filled with copper oxide nanofillers.

Nanofibers based on polyvinylidene fluoride-trifluoroethylene/poly(3-hexylthiophene) (P(VDF-TrFE)/P3HT) containing copper oxide nanoparticles (CuO NPs) were fabricated using the electrospinning technique. Scanning electron microscope (SEM) images revealed smooth, bead-free solid nanofibers of 34-100 nm diameters. X-ray diffraction (XRD) analysis shows the ferroelectric β phase of P(VDF-TrFE) with a wide diffraction pattern.
