Abstract
Nature has begun to inspire scientists and engineers world-wide to create/modify surfaces, as novel means to find solutions for various technical issues in real-time applications. In the field of nano/micro-tribology, the superhydrophobic property of the Lotus leaf surface popularly known as the “Lotus Effect” has been of prime inspiration. The creation of these bio-mimetic surfaces has been aimed at providing solutions to the tribological issues found in miniaturized devices such as micro/nano-electro-mechanical-systems (MEMS/NEMS). The bio-mimetic surfaces in this report involve polymeric micro-patterns that replicate morphology of the Lotus and Colocasia leaves and silicon nano-patterns on silicon surfaces. The silicon patterns were further modified by coating lubricant thin films. These surfaces were characterized for their hydrophobic property and tribological properties at nano/micro-scales. Results showed that the bio-mimetic surfaces outperformed the bare silicon surfaces. The main reasons for such an occurrence include the hydrophobic nature of the patterned surfaces and the reduced real area of contact projected by them
