#Controlling ice formation on gradient wettability surfaces for high-performance bioinspired materials
“#Controlling ice formation on gradient wettability surfaces for high-performance bioinspired materials” Freeze-casting technique using copper surfaces with different wettability and the resulting scaffolds. SEM images were taken from the cross section of 1-cm height parallel to the cold surface. (A to D) When freezing on the homogeneously hydrophilic and hydrophobic copper substrates, the ice crystals…
