• The results of an investigation into the effects of modifying a surface layer (SL) of polylactide (PLA) as a function of time are presented. The PLA modification was performed by the method of corona discharges (CD) in the air using unit energy values (E sub(u)) equal to 3.5 and 10 kJ/m super(2). The extent of oxidation and contact angle of the SL were determined by the methods of X-ray photoelectron spectroscopy (XPS) and goniometry, respectively. The measurements were carried out immediately after the modification process, as well as 1, 2, and 3 months later.Original Abstract: Analizowano zanik w czasie zmian wywolanych modyfikowaniem za pomoca wyfadowan koronowych (CD) warstwy wierzchniej (SL) polilaktydu (PLA). Modyfikowanie prowadzono w atmosferze powietrza, z zastosowaniem jednostkowej energii (E sub(u) modyfikowania o wartosci 3,5 i 10 kJ/m super(2). Stopien utlenienia oraz wartosc kata zwilzania SL badano metoda spektroskopii fotoelektronowej (XPS) oraz goniometrii, bezposrednio po procesie modyfikowania oraz po uplywie 1, 2 i 3 miesiecy.
