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.... （请下载全文欣赏）
