On the correlation of surface charge and energy in non-thermal plasma-treated polyethylene

Popis výsledku v původním jazyce

Non-thermal non-equilibrium oxidative air 40-kHz frequency, 13.56-MHz radiofrequency and 2.46-GHz microwave discharge plasma treatment were used for modifying low-density polyethylene foils. The untreated and treated samples were chemically characterisedby X-ray photoelectron spectroscopy. In order to estimate the extent of the plasma sources at distinct treatment times, surface charge and energy were determined by zeta potential (zeta) and surface tension measurements. In addition, the isoelectric points (IEPs) of the studied samples were ascertained, and surface property variations were appraised by ageing time. The overall outcome indicated that zeta-potential and surface energy progressively changed after each treatment, as well as the influencesof ageing on surface features, the IEP shifting to lower pH values and how all of these changes are associated with the new surface chemistry. This contribution seeks to shed light on topics related to polymer science and plasma-based str
