Abstract
The stability of plasma polymerised layers has become important because of their widespread use. This study explored the hydrolysis and
degradation stability of coatings of plasma polymerised maleic anhydride. Coatings made with different plasma parameters were exposed to
aqueous media of different pH as a function of time. ATR-FTIR was used for structure analysis and a toluidine blue staining method allowed
quantitative analysis of the hydrolysis of anhydride groups to acid groups. Coatings with constant thickness were obtained at different plasma
powers and layers with varying thickness were obtained at constant plasma power by adjusting the polymerisation time. The results show that the
hydrolysis resistance of the modified layer is determined by the power used in the plasma polymerisation, while changes in the chemistry of the
modified layer are insignificant.
