Based on the cell discrepancy of parenchyma and sclerenchyma, ZnO was selectively built on the surface of bamboo to prepare a hydrophilic–hydrophobic wettability surface. The results revealed that ZnO nanoparticles were successfully cultivated on the surface of bamboo, and the distribution of ZnO was definitely denser in the bamboo parenchyma cell region with nanocrystal differences. The contact angles of the parenchyma and fiber regions of modified bamboo were 109.6±4.5° and 43.3±6.0°, respectively. In addition, SiO2-loaded ZnO bamboo was obtained by dipping in silica solution. Surface element analysis demonstrated that the solution could selectively wet the bamboo hydrophilic fiber region. In addition, octadecyltrichlorosilane was used to modify ZnO bamboo by spraying with an air brush. Droplet slide experiments indicated that the functional surface could control the movement of water droplets.
