In contrast, when submerged in ethanol, the EGaIn droplet becomes highly non-wetting, forming a contact angle of nearly 180 • , with no adhesion and negligible hysteresis in the force spectroscopy curves. A hysteresis-free force curve means that the EGaIn contact area in ethanol only depends on the magnitude of the applied force (i.e., conservative) and not on how the applied force is achieved (i.e., path and rate independent); in contrast, the contact area in air can take on different values for the same magnitude of the applied force (i.e., non-conservative).
