  • Fig. 2 is a photograph of a prototype created for experimental purposes.
  • Figs. 7a-7d are photographs of a droplet moving across a wettability gradient.
  • the structure disclosed herein can be used in the field of microfluidics such as lab-on-a-chip devices.
  • the structure disclosed herein can be used to drive fluid droplets across a surface without the need for channels. This functionality can result in less contamination and more flexibility in fluid delivery since the fluid can be driven to any point on the surface and not limited by paths set by channels.
  • This functionality has many applications including drug, fluid, and nutrient delivery, cell and tissue culture platforms, and high-throughput assays.
  • the polymer can be used as a coating on pipes, submarines, boats, or any other water vehicle.
  • the friction coefficient between water and the polymer In the superhydrophobic, non-wetting state, the friction coefficient between water and the polymer is extremely low. In the superhydrophilic wetting state, the friction coefficient between water and the polymer is high.
  • the polymer can be switched to the non-absorbent state thereby allowing the vehicle to move very fast since drag has been reduced. When the polymer is switched to the absorbent state, drag is increased and the vehicle can slow down much faster than without the coating.
  • weatherproof materials can utilize the polymer coated on clothing or other products such as camping gear, umbrellas, and boots that need to be waterproof.

Abstract

La présente invention a trait à une structure dotée d'une mouillabilité qui peut changer électriquement. La structure comprend un polymère conducteur dopé, une contre-électrode et un électrolyte situé entre ledit polymère conducteur dopé et la contre-électrode. Du polypyrrole dopé aux ions de carbone fluoré constitue un polymère conducteur préféré. Une tension entre le polymère conducteur dopé et la contre-électrode amène ledit polymère conducteur à passer d'un état hydrophobe à un état hydrophile, et inversement.
