Porous media evaporator

An evaporation system, comprising:

• one or more evaporation assemblies, each of the one or more evaporation assemblies comprising:
• an evaporator body, comprising:
• an evaporator sidewall;
• an evaporator volume defined by the evaporator sidewall;
• and
• an opening defined by the evaporator sidewall;
• and
• a coating material basin, comprising:
• a basin sidewall;
• a coating material volume defined by the basin sidewall;
• a coating material bath disposed in the coating material volume;
• and
• a porous media partially disposed in the coating material bath and partially disposed within the evaporator volume.

A method of coating a substrate, comprising:

• providing a substrate to an evaporation system;
• feeding a coating material into an evaporator;
• heating a porous media of the evaporator;
• absorbing the coating material into the porous media;
• evaporating the coating material to form a coating material vapor;
• and
• coating the substrate with the coating material vapor.
