a Scheme of the grooved PDMS, W refers to the width of the convex part of the groove, D refers to the width of the concave part of the groove, and λ is the width of one groove composed of one convex part and one concave part. b Schemes of three ice orientations, including random orientation, the orientation parallel and perpendicular to surface grooves. c Summarized alignment of the microstructures obtained by freezing on grooved PDMS surfaces with various W and D. d The phase diagram of the λksuspension and W/D. The symbol of crisscross lines (\(\times\)) refers to random orientation, the symbol of parallel lines (\(\parallel\)) refers to the orientation parallel to the grooves, and the symbol of vertical lines (\(\perp\)) refers to the orientation perpendicular to the grooves, the definition of the symbols is applied for all colors.
