An original and low cost method for the fabrication of patterned surfaces bioinspired from butterfly wings and lotus leaves is presented. Silica-based sol-gel films are thermally imprinted from elastomeric molds to produce stable structures with superhydrophobicity values as high as 160 degrees water contact angle. The biomimetic surfaces are demonstrated to be tuned from superhydrophobic to superhydrophilic by annealing between 200 degrees C and 500 degrees C.
本文提出了一种受蝴蝶翅膀和荷叶启发制备图案化表面的原创且低成本方法。基于二氧化硅的溶胶 - 凝胶薄膜通过弹性体模具进行热压印，以产生具有高达160度水接触角的超疏水稳定性结构。实验证明，通过在200摄氏度至500摄氏度之间进行退火处理，可使仿生表面从超疏水转变为超亲水。
