• determine the dielectric constant, refractive index and the thickness of the obtained fibrous mats. Keywords: ceramic nanoparticles; electrospinning methods; polyacrylonitrile; polymer composite nanofibres; spectroscopic ellipsometry; Introduction Over the last decade, there has been a noticeable

• produced by using electrospinning from solutions of polymers based on polyacrylonitrile (PAN) and N,N-dimethylformamide (DMF) with ceramic nanoparticles of SiO2/TiO2/Bi2O3. PAN/SiO2 composite nanofibres are used as membranes in the production of air filters, gas absorbents and new types of lithium-ion

• 25 nm. The microscopic study for the analysis of TEM images of particles and the analysis of SEM images of the fibrous surface topography of the composite mats allowed us to determine the influence of the diameter of the applied ceramic nanoparticles on the structure and the morphology of the
