Fig. 8: Effects of different microcones heights on the recovery of CB state.

a State changes of droplets on the MCNP surfaces with different microcones heights after an icing & melting cycle. b Morphology evolutions of micro-nanostructure with different microcones heights. By adjusting laser processing parameters (Supplementary Table 2), we achieve precisely tunable heights and pitches of the micro-nanostructure on the MCNP surfaces. Two kinds of surfaces are fabricated: the surfaces with different microcones heights and constant pitch and the surfaces with different microcones pitches and constant height (Supplementary Figs. 20–22 and Supplementary Method 2). In the figure, microcones pitch is fixed at 35 μm while microcones heights vary from 35 μm to 55 μm. c–e Effects of different microcones heights on the contact diameter recovery rates (CDRR), the contact angle recovery rates (CARR), contact angles (CA), and sliding angles (SA), respectively. The CA 150° and SA 10° boundaries of superhydrophobicity are indicated with the black dashed line. Data are mean ± s.d. from at least three independent measurements.
