A simple approach to fabricate the rose petal-like hierarchical surfaces for droplet transportation

Abstract: Precise transportation of liquid microdroplets is a great challenge in the microfluidic field. A sticky superhydrophobic surface with a high static contact angle (CA) and a large contact angle hysteresis (CAH) is recognized as the favorable tool to deal with the challenging job. Some approaches have been proposed to fabricate such surface, such as mimicing the dual-scale hierarchical structure of a natural material, like rose petal. However, the available approaches normally require multiple processing steps o… Show more

“…The present methods using superhydrophobic surfaces to manipulate droplets can be divided into two types: non-in-situ control and in-situ control. Non-in-situ control often uses gecko feet/rose petal/mussel-inspired superhydrophobic surfaces to manipulate droplets [12][13][14][15][16][17][18][19][20][21][22]. These surfaces are also called high adhesive superhydrophobic surfaces which allow water droplets to adhere to the surfaces even when the surfaces are turned upside down but still with water CAs larger than 150°.…”

“…O trabalho de Xu et al (2009) destaca que podemos encontrar organismos vivos que apresentam propriedades de superhidrofobia na natureza, como a flor de lótus, que tem a sua superfícies totalmente rugosa, na qual são formadas cavidades ocupadas pelo ar atmosférico, não deixando as gotículas de água penetrarem na flor. Inspirados na natureza, diversos autores (Xu et al, 2009;Xue et al, 2010; Park e Hwang, 2016;Ou et al, 2015;Yuan et al, 2016) propuseram diferentes métodos para o desenvolvimento de superfícies superhidrofóbicas artificiais.
