Biomimicked Polymer Surfaces Exhibiting Superhydrophobic And Anti-reflective Properties
Project Description :

The structure of seedpod, petal and leaf of canna indica l. was biomimicked using various polymers and then studied for their wettability characteristics. the biomimicked polymer surfaces were found to exhibit superhydrophobicity. the superhydrophobic nature of the seedpod with high aspect ratio and hierarchical patterns having much larger surface area were not only preserved but also slightly improved in the rf gel replica. the petal and leaf bimimicked polymer surfaces with multi-scale surface patterns were further studied for their antireflective properties. the biomimicked high aspect ratio micron features as found in canna indica petal and leaf demonstrated near zero reflection for a wide range of wavelength and incidence angle of light. the fabrication of superhydrophobic as well as antireflective polymer surface using this low cost simple biomimicking technique opens possibilities of use in a variety of applications like solar cells, self-cleaning materials, microfluidics and energy storage devices.
