Analysis of the decay of some effects of modification of polylactide surface layers (in English)
Polimery 2015, No 7-8, 462
The results of an investigation into the effects of modifying a surface layer (SL) of polylactide (PLA) as afunction of time are presented. The PLA modification was performed by the method of corona discharges (CD) in the air using unit energy values (Eu
) equal to 3.5 and 10 kJ/m2
. 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.
