Abstract
A method of making an electrocaloric element includes forming conductive layers on opposing surfaces of a film comprising an electrocaloric material to form an electrocaloric element, wherein the forming of the conductive layers includes one or more of: vapor deposition of the conductive layers under reduced pressure for a duration of time, wherein the duration of time under reduced pressure is less than 240 minutes; vapor deposition of the conductive layers under reduced pressure for a duration of time, wherein the duration of time of exposure to conductive material deposition is less than 240 minutes; vapor deposition of the conductive layers under reduced pressure, wherein the reduced pressure is 10torr to 500 torr; or maintaining the film at a temperature of less than or equal to 200° C. during forming of the conductive layers.
