BIO-INSPIRED TEXTURES FOR DRAG REDUCTION

BIO-INSPIRED TEXTURES FOR DRAG REDUCTION

Details

 
Omniphobic surfaces, which repel all liquids, are used in numerous applications, including desalination and drag reduction. Typically, these surfaces exploit perfluorinated chemicals that are expensive, non-biodegrada-ble, and vulnurable to harsh physical conditions. In response, we have recently demonstrated that bio-inspired doubly reentrant microtextures could render even intrinsically wetting surfaces temporarily omniphobic. Currenlty, we are investigating mechanisms underlying time-dependent wetting transitions along with practical applications.
