Dual effect of CuO particles on electrospinning process and properties

Popis výsledku v původním jazyce

In the present research work polyurethane (PU) nanofibers with different concentrations (0,5; 1; 5%) of CuO particles by electrospinning according Nanospider technology in the form of roll electrode against flat electrode. CuO particles were introduced into the polymers solution before fiberforming. The effect of catalysts on the viscosity of solutions was recorded only for a concentration 5%.SEM results confirmed well oriented nanofibers and good distribution of CuO particles. Average index of surfacedensity for samples of pure PU fibers 2.8 g/m^2, for PU/CuO(5%) is 12,257 g/m^2. So particles of CuO promote to the proces sof electrospinning and increase its performance due a conductive properties of copper. The microorganisms Escherichia coli and Staphylococus aureus have been used to determine the antimicrobial efficiency of these samples. Good bactericidial prolongation effect was indicated for prepared nanofibers. Efficiency of the filtration properties was measured for pure PU an
