Abstract:

The aim of study was to produce a nanocomposite polymer fibrous thin films, with the participation of the reinforcing phase in the form of TiO2/Bi2O3/SiO2 nanoparticles with a matrix of polyacrylonitrile (PAN), made by electrospinning of solution and investigation of optical and eletrical properties of obtained nanomaterials. To determination of structore of used ceramic nanoparticles the X-ray diffraction analysis (XRD) was carrying out. The morphology of the obtained polymeric and composite fibrous mats and dispersion of nanoparticles in their volume was examined using scanning electron microscopy (SEM). All the physical properties of which were: the dielectric constant, and refractive index were tested and plotted against the concentration by weight of the used reinforcing phase which was as follows: 0%, 4%, 8%, 12% for each type of nanoparticles. The optical and electrical constants of obtained thin folms was performed on the basis of UV-Vis spectra of absorbance as a function of the wavelength. Using two metods: the method proposed by the author and the recorded absorbance spectra and spectroscopic ellipsometry determined the refractive index n, real n' and imaginary k part of the refractive index as a function of the wavelength, complex dielectric permeability , real and imaginary part r and i of the dielectric permeability as a function of the wavelength of the polimeric and composite fibrous thin films.
