| Popis | In presented work we compare the influence of low-temperature plasma generated in ambient air by Diffuse Coplanar Surface Barrier Discharge on three types of most commonly used polymers - polyvinylpyrrolidone, polyvinyl alcohol and polyacrylonitrile with suitable precursors. Samples were studied in terms of chemical composition (ATR-FTIR, EDX) and surface morphology (SEM). The method was studied as a separate treatment or pretreatment procedure before thermal calcination. Thanks to the high power density of generated plasma and related high density of active particles, a significant removal of the organic part of the hybrid fiber without the damage of the fibrous structure was observed in the first 30 minutes. Plasma treatment before sintering decreases the time and temperature needed to complete removal of organics, does not require slow temperature rise and so decreases the cost and simplifies the preparation of metal oxide fibers. |
