The purpose of this work was to study the effects of low-pressure oxygen plasma treatment on the surface characteristics of kevlar fabric. For comparison purposes, samples treated with oxygenated plasma were prepared and characterised under different experimental conditions, i.e. a treatment time variation of 10, 30 and 60 minutes under a constant pressure of 4 mBar, using a pulsed current source. We analysed the effects of chemical and physical changes to the surface of the material aiming at improved hydrophilicity attributed to the formation of roughness on the surface of fibres, thus obtaining optimal parameters for future works. Changes in the chemical composition of the surface as well as in the superficial roughness of fibres before and after treatment were determined by FTIR, TGA, XRD and wettability testing. SEM was used as a complementary technique to monitor the changes triggered by the procedures using oxygen plasma.

Celem pracy było zbadanie wpływu obróbki niskociśnieniową plazmą tlenową na właściwości powierzchni tkaniny “kevlarowej”. Dla celów porównawczych przygotowano próbki poddane działaniu plazmy natlenionej i scharakteryzowane w różnych warunkach eksperymentalnych, tj. zmiennym czasie obróbki wynoszącym 10, 30 i 60 minut pod stałym ciśnieniem 4 mBar, przy użyciu źródła prądu pulsacyjnego. Przeanalizowano wpływ zmian chemicznych i fizycznych na powierzchni materiału, mając na celu poprawę hydrofilowości związanej z powstawaniem chropowatości na powierzchni włókien, uzyskując w ten sposób optymalne parametry dla przyszłych eksperymentów. Zmiany w składzie chemicznym powierzchni, a także w chropowatości powierzchni włókien przed i po obróbce określono za pomocą FTIR, TGA, XRD i testów zwilżalności. SEM zastosowano jako technikę uzupełniającą do monitorowania zmian wywołanych procedurami z wykorzystaniem plazmy tlenowej.
