Abstract The aim of this study is to explore the heterogeneous ice nucleation
behavior based on controllable micro-cubic array structure surfaces from the statistic perspective. To this end, we firstly constructed a group of micro-cubic array
structures on silicon substrates by a selective plasma etching technique. After
grafting low-free-energy substance, the as-constructed micro-cubic array structure
surfaces exhibited higher non-wettability with the water contact angle being up to
150°. On this basis, 500 cycles of freezing and melting processes were accurately
recorded to analyze the instantaneous ice nucleation behavior according to the statistical results of freezing temperature. As a consequence, the statistical… More >
