The present invention is the formation of solid polymer layers under vacuum. More specifically, the present invention is the use of "standard" polymer layer-making equipment that is generally used is an atmospheric environment in a vacuum, and degassing the monomer material prior to injection into the vacuum. Additional layers of polymer or metal or oxide may be vacu- um deposited onto solid polymer layers. Formation of polymer layers under a vacuum improves material and surface characteris- tics, and subsequent quality of bonding to additional layers. Further advantages include use of less to no photoinitiator for cur- ing, faster curing, fewer impurities in the polymer electrolyte, as well as improvement in material properties including no trapped gas resulting in greater density, and reduced monomer wetting angle that facilitates spreading of the monomer and provides a smoother finished surface.
