Abstract: | Highly ordered radially aligned microchannels are produced on the surface of polymer nanocomposite thin films via droplet evaporation. This simple, rapid, and cost-effective approach opens a new avenue for producing macroscopic surface patterns that have potential as scaffolds or substrates in the field of microelectronics or microfluidic-based biochips. |
