"Webent time intervals. The contact angles were calculated using Eq. (1) and plotted on a contact angle versus time curve. The contact angle at time zero, θ 0, was obtained by extrapolating the first part (about 1 s) of the curve by linear regression. By extrapolating to θ 0, the effect of roughness and absorption can be disregarded. " - Fibrodat contact angle
