ABSTRACT
Biaxially oriented PP film (BOPP) was treated by low-temperature plasma generated by corona discharches in air. The specific treating energy changed from to 0 to 15 kJ/m2 The influence of specific treating energy on free surface energy, oxidation degree of outer layer (OL) of polymer and surface roughness of treated film has been investigated. The free surface energy was determined by Owens – Wendt's and van Oss – Good's methods. The oxidation degree of OL was determined by XPS method and surface roughness by AFM method. The influence of specific treating energy on adhesive strength of joints with treated film was also investigated.

plazma niskotemperaturowa, modyfikowanie właściwości warstwy wierzchniej folii
Folię polipropylenową dwukierunkowo orientowaną (BOPP) aktywowano w wy ładowaniu koronowym o jednostkowej energii od 0 do 15 kJ m–2, w atmosferze powietrza. Badano zależność swobodnej energii powierzchniowej, stopień utlenienia warstwy wierzchniej (WW) i chropowatość powierzchni aktywowanej folii, a także wytrzymałość adhezyjną złącz z aktywowaną folią od jednostkowej energii aktywowania. Swobodną energię powierzchniową określano metodami Owensa – Wendta oraz van Ossa – Gooda. Stopień utlenienia WW bada-no metodą XPS, a chropowatość powierzchni metodą AFM.
