Abstract
In this research, we replicate the hierarchical structures of rose petals by using poly urethane acrylate (PUA) nanomolding technology. After a molding process, we use a PUA replica as the mother mold for nickel electroforming processes. By replicating the original rose petal hierarchical structure, we obtain the rose petal effect with nickel substrates. In order to make a negative-patterned nickel stamp, a second PUA replication was done using the first PUA mother mold and a nickel electroforming process was performed. Using these, the hierarchical structure of rose petals was imprinted in perfluoropolyether (PFPE), which exhibited the petal effect.
