Reversible Super-hydrophobicity to Super-hydrophilicity Transition of Aligned ZnO Nanorod Films Wettability is a very important property governed by both the chemical composition and the geometrical structure of solid surfaces. 1 Super-hydrophobic surface (with water contact angle (CA) larger than 150°) and super-hydrophilic surfaces (CA close to 0°) have been extensively investigated due to their importance for industrial applications.... （請下載全文欣賞）
