Dataset for: Comparison of sputtered thin copper films and metallic spray coatings on PET substrates for metallic appearance

This dataset contains experimental data supporting the study on metallic coatings on PET substrates. The dataset includes:– Gloss measurements (GU) for spray and sputtered copper coatings– Coefficient of friction (COF) values from tribological testing– Thickness measurements obtained by profilometry– Surface roughness parameters obtained by AFM The data correspond to coatings prepared by DC magnetron sputtering and metallic spray application on PET substrates. These data support the findings presented in the associated publication.
