We present a simple and scalable approach to fabricate arrayed nanowire structure using combined techniques of colloidal nanolithography, deep-silicon etching, and nanomolding 1) to mimic the nanostructure of gecko foot-hairs, and 2) to fabricate transparent and flexible electrode. The artificial surface features densely packed polymeric nanopillars structure and 2 D arrayed flexible carbon nanotube based polymer sheet. The method allows both fabrication of synthetic structures in large area and direct integration of flexible membrane to assist the array of “nanohairs” in making intimate contact with the uneven surfaces. Our results indicate that a single “nanohair” exhibit a mean adhesive force of 1.84 nN. In the macroscopic scale, we demonstrate that the nanostructured surface can adhere firmly to a smooth glass substrate and inherit the self-cleaning property of the setal nanostructures found in gecko lamellae. And it was found that thickly coated carbon nanotube network showed superior conductivity to the thinly coated one, however the transparency loss due to the increased carbon nanotube packing density was controlled at the level of 10 % of the incident light using a light having 650 nm wavelength. |
