In this paper, a novel method for the measurement of equilibrium contact angle of highly volatile binary liquids is proposed. The proposed computational method, which combines finite element method and energy equilibration, calculates the solid-liquid contact area, which can then be used to estimate the equilibrium contact angle. Using the proposed approach, the contact angles of binary-liquid droplet on a microgrooved and smooth polycarbonate substrate were calculated. The proposed method is found to be an efficient tool for finding the contact angle of all liquids (both volatile and non-volatile).
