Hysteresis comparison immediately following water
vapor condensation investigated by moving the substrate in
one direction (moving to right): a, before water condensation,
advancing CA: 169.5°, hysteresis 4.1°; b, immediately after
water condensation, advancing CA: 166.0°, hysteresis 19.4°;
c, because the previous water droplet removed the
condensate, the surface shows improved hysteresis, advancing
CA: 168.3°, hysteresis 4.5°.
