Abstract Ultraviolet/ozone (UV/O3) treatment has been reported to be an effective method to
modify properties such as wettability, adhesion or adsorption of plastic surfaces. The change
in the surface is measured by contact angle analysis, which employs liquids and their
surface tensions (ST) to estimate the surface energy (SE). We found two different practices in
the scientific community:(1) the majority of researchers adopted the ST value of liquids from
the literature, while (2) other researchers conducted real-time measurements in the lab …
