The leaves of certain plants, such as lotus and rice, contain superhydrophobic surfaces. These plants have been widely studied because of their unique water repellent and self-cleaning characteristics. Such unique features, known as the lotus effect, are mainly attributed to micro- and nano-scale surface structures, as well as the chemical composition of wax on the surface. We investigated the wettability and impact dynamics of water droplets on rice leaves at various leaf inclination angles and orientations. Contact angle, contact angle hysteresis, and roll-off angle of water droplets were me...
