A process for producing a patterned deformable polymer film for use in a deformable polymer device is disclosed. The process includes positioning an intermediary layer between a deformable film and a process tooling and printing at least one electrode on the deformable film by depositing an ink to form the at least one electrode on a first surface of the deformable film, wherein the intermediary layer permits release of the deformable film from the process tooling subsequent to the printing process. Films produced by the inventive processes may find use in electroactive polymer devices.
1. A process for producing a patterned deformable polymer film for use in a deformable polymer device, the process comprising: supporting a deformable film section such that the deformable film section comprises a supported portion and an unsupported portion;positioning an intermediary layer between
