Purpose: This paper describes the effect of inorganic additives and operating parameters of an electrospinning process on electrospun fiber diameters and morphology. Design/methodology/approach: Application of different solvents and process parameters impact characteristics of the micro and nanofibers made of PEO and also PVA with CuOAc. Findings: The results show that the three parameters (volumetric charge density, distance from nozzle to collector, and viscosity) have the most significant effect on the electrospun fiber morphology. The nano- and microfibers produced were characterized by scanning electron microscopy as well as with use of image analyzing tool DigitalMicrograph. Changes in length of stream and volatility of the solvent influence the shape of the fibres and internal solution load. The resulting fibre shape shows that for shorter distances the process was unstable, and the morphology of the filaments from a longer distance shows the gradual stabilization and indicates optimal process parameters. Practical implications: Based on the research carried out it is clear that micro and nanofiber characteristics vary widely depending on prepared solutions and process parameters. Originality/value: It was confirmed that inorganic additives, solvent type and process parameters have an effect on morphological aspects of produced micro and nanofibres.
