For example, copolymers of p-hydroxybenzoic acid can be appropriate liquid crystal polymer base polymers. Copolymers including monomers of the listed polymers and mixtures of these polymers may also be used. Non-limiting examples of the polymers used in this aspect of the invention can be selected from the group including PPS, Poly(p-phenylene oxide) (“PPO”), LCPs, Polyether ether ketone (“PEEK”), Polyphthalamide (“PPA”), Polypyrrole, Polyaniline, and Polysulfone. In both cases where the heteroatom is located on the backbone or bonded to a carbon atom positioned on the backbone, the backbone atom is positioned on the backbone adjacent to an aromatic ring. The heteroatom can be located directly on the backbone or bonded to a carbon atom which is positioned directly on the backbone. In an aspect, polymers useful as reactants can possess an aromatic or heterocyclic component in the backbone of each repeating monomer group, and a heteroatom either incorporated in the heterocyclic ring or positioned along the backbone in a position adjacent the aromatic ring. The film is heated to complete the synthesis. In an aspect of the synthesis method, all three components are mixed and then extruded into a film. The heating step can be performed regardless of the form of the mixture (e.g. However, this heating step can be done when in a separate step from any mixing or can completed while mixing is being done. All three components can be present and mixed and heated to complete the synthesis of the solid ionically conducting polymer material in a single step. If the dopant was not present in the mixture produced in the first step, then it can be subsequently added to the mixture while heat and optionally pressure (positive pressure or vacuum) are applied. In one aspect of the invention, the resulting mixture can be optionally formed into a film of desired size. However, the method includes the basic steps of mixing at least two of the components initially, adding the third component in an optional second mixing step, and heating the components/reactants to synthesize the solid ionically conducting polymer material in a heating step. The method of synthesis can also vary depending on the particular components and the desired form of the end material (e.g.
