      abstract     = {Polar and dispersion surface free energy (SFE) can be
                      determined with the Owens-Wendt method. Thereby, contact
                      angles (CAs) of at least two liquids with known surface
                      tension (ST) components are measured. The ST components can
                      either be determined through experiment or drawn from
                      literature. However, it is important to know how big the
                      difference is between SFE component values that have been
                      calculated with experimentally-determined ST values or
                      values derived from literature. In this study, STs of
                      different test liquids were analyzed by Pendant Drop method
                      and the components by CA measurement on a non-polar surface.
                      CAs on different polymer surfaces were measured to calculate
                      SFE components with the Owens-Wendt method. The calculations
                      conducted were either based on experimentally-determined ST
                      parts or different sets of values found in the literature.
                      The findings of the survey show that, depending on the set
                      of literature values used, the SFE results deviate
                      significantly from the values obtained from experiment.
                      Expressing this deviation in figures, in extreme cases the
                      polar part differs for some polymers by $-100\%$ to
                      $+100\%,$ with the dispersion component spanning $-50\%$ to
                      $+43\%.$ In comparison, the expected relative uncertainties
                      exhibited by the experimentally-determined ST values are
                      about $15\%$ for the polar and approximately $5\%$ for the
                      dispersion SFE part. Hence, the results show that the SFE
                      uncertainty can be reduced significantly by means of
                      analyzing the ST parts experimentally.},
