Abstract
A superhydrophobic polymer fabrication is provided. According to one method for preparing a superhydrophobic polymer fabrication, the superhydrophobic polymer fabrication can be fabricated quickly and easily, and the superhydrophobic surface can be repeatedly imprinted using a template, so that mass production of the superhydrophobic polymer fabrication over a large area can be economically implemented.
Claims18
A method of preparing a superhydrophobic polymer fabrication, comprising:
- forming a micron-sized terrace structure on a surface of a template and a nano-sized groove structure within the terrace structure by chemical etching, wherein the micron-sized terrace structure comprises irregularly distributed fragments;
- applying heat and pressure to a polymer placed on the etched template to replicate a polymer fabrication from the etched template;
- and
- removing the replicated polymer fabrication from the template.
