Numerical and Experimental Research of Design Optimization of Baths for the Production of Nanofibers by the Electrospinning

Popis výsledku v původním jazyce

A study and analysis showed that the increase in production and the quantity of nanofibers obtained from electrospinning may be provided by not only increasing the potential gradient between the electrodes, but also by the suitable distribution of the intensity of the electrostatic field. Through a numerical simulation using the finite element method, it was found that the intensity distribution of the electrostatic field is influenced not only by the potential gradient, type and shape of the electrodes, polymer properties and its concentration, humidity, ambient temperature, but also by other parameters, such as relative permittivity of the material and shape of the construction geometry. Experiments have been done with the functional baths for polymer solution deposition with a different geometry and relative permittivity. By using the proposed changes in design and relative permittivity for the experiment with the polymer PVP with TiO2 at 23.2 ? 3 °C and humidity of 14.4 ? 3% and a
