New method for determining paper surface energy per contact angle

We propose a new method for determining the surface energy of paper and its components using the contact angle technique. Calendered sheets and model liquids were used in this study. A rapid evolution of the probe/handsheet contact angle with time was observed for all tested conditions. A suitable m...

Description
Summary:We propose a new method for determining the surface energy of paper and its components using the contact angle technique. Calendered sheets and model liquids were used in this study. A rapid evolution of the probe/handsheet contact angle with time was observed for all tested conditions. A suitable method for choosing the contact angle and a new model to determine the surface energy and its components is proposed. The total surface energy of paper hansheets (47.2–50.4 mN m −1 ) and its components (dispersive γ d  ~ 19–20, polar γ p  ~ 4–5 and hydrogen bond γ h  ~ 25–32) are in good agreement with literature data.
