The superhydrophobic structure created on the bamboo surfaces is similar to that of the lotus leaf after twice replication, with fresh lotus leaves as the template and the polydimethylsiloxane(PDMS) as the seal. The results of the scanning electron microscopy(SEM) and the water contact angle(WCA) measurements show that the prepared bionic lotus-leaf bamboo samples enjoy lotus-leaf-like micro-nano papillary rough surfaces. The WCA is 150.5°(the average value), very close to that of lotus leaf surfaces(154.5°), displaying a super-hydrophobic property. The successful preparation of the bionic lotus leaf micro-nano structure samples confirms the feasibility that a super-hydrophobic surface on bamboo and other hydrophilic materials could be achieved with the nano-technology.
