By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Biomimetics have been published. According to news reporting from Changchun, People's Republic of China, by NewsRx journalists, research stated, "Triggered by the microstructure characteristics of the surfaces of typical plant leaves such as the petals of roses, a biomimetic superhydrophobic surface with high adhesion is successfully fabricated on aluminum alloy. The essential procedure is that samples were processed by a laser, then immersed and etched in nitric acid and copper nitrate, and finally modified by DTS (CH3(CH2)(11)Si(OCH3)(3))."
The news correspondents obtained a quote from the research from Jilin University, "The obtained surfaces exhibit a binary structure consisting of microscale crater-like pits and nanoscale reticula. The superhydrophobicity can be simultaneously affected by the micronano binary structure and chemical composition of the surface. The contact angle of the superhydrophobic surface reaches up to 158.8 +/- 2 degrees. Especially, the surface with micronano binary structure is revealed to be an excellent adhesive property with petal-effect. Moreover, the superhydrophobic surfaces show excellent stability in aqueous solution with a large pH range and after being exposed long-term in air. In this way, the multifunctional biomimetic structural surface of the aluminum alloy is fabricated."
According to the news reporters, the research concluded: "Furthermore, the preparation technology in this provides a new route for other metal materials."
