Controlled spreading of thermo-responsive droplets.
A novel methodology for controlling the spreading of droplets impacting a substrate is presented. The working fluid is a thermo-responsive polymer solution that undergoes a sol-gel transition above a specific temperature. It is shown that the maximum diameter of a droplet at equilibrium can be controlled through the substrate temperature of the substrate and the polymer concentration.
