Abstract
An apparatus for distributing a hydrophobic material in a hydrophilic substrate includes a first plate, a second plate, a heater operatively connected to the first plate and configured to heat the first plate to a first temperature that is greater than a second temperature of the second plate, and an actuator configured to move the first plate and second plate together with a hydrophilic substrate between the plates. The first plate and second plate form a temperature gradient to enable a hydrophobic material on one side of a hydrophilic substrate that faces the second plate to penetrate into the hydrophilic substrate towards the first plate.
