Plasma polymer films are more and more used in numerous applications such as the day-to-day packaging, which requires a good mechanical resistance of the coating. Since mechanical properties are function of the cross-linking degree of the thin films, it is important to understand the relationship between the two. In this work, plasma polymer films were studied in terms of cross-linking degree and mechanical properties, measured by means of ToF-SIMS coupled to PCA and depth-sensing nanoindentation, respectively. The data reveal that when the power increases, the films are more cross-linked and show higher hardness, higher elastic recovery, lower creep strain and an increased ability for self-healing. As the plasma polymer films are more cross-linked, the plasticity drops and the viscoelasticity and hardness increase. [ABSTRACT FROM AUTHOR]
