Preparation and Dielectric Property Investigation of Ferrocene/Poly(vinyl pyrrolidone) Composite Membranes
The ferrocene/Poly(vinyl pyrrolidone) (PVP) composite membranes have been successfully prepared by using electrospinning and polarization coating techniques, respectively. The composite membranes were characterized by means of SEM (scanning electron microscopy), UV-vis absorption spectra,
FT-IR (Fourier transform infrared), XRD (X-ray diffraction) and a radio frequency (RF) impedance/capacitance material analyzer. Results showed that the dielectric constants of the ferrocene/PVP composite nanofiber membranes were lower than the coating membranes. The dielectric constants of
nanofiber membranes were decreasing with the increasing amount of ferrocene in the solvent, but those of coating membranes were increasing with the increasing amount of ferrocene.
