Polymer blending is a technique of interest that has captured the attention of numerous research groups since the twentieth century to the present day. Pioneering studies in the development of high-performance polymer electrolytes has mainly been focused on the use of single types of preformed polymers, such as poly(ethylene oxide) (PEO), poly(methyl methacrylate) (PMMA), and poly(vinyl chloride) (PVC). However, as the properties of the homopolymer-based electrolytes were unable to support the applications of high-conducting electronic devices in many ways, an alternative approach was sought which involved the blending of two or more preformed polymers of different natures to form an ionic conducting matrix [1,2].During subsequent years, the conducting matrix underwent development by employing copolymers synthesized from mixtures of monomers, and consequently the formulation of brand new polymers via the polymerization process captured the attention of many research groups. Unfortunately, however, most synthetic efforts cannot guarantee the creation of polymers that will meet the entire needs of research groups in terms of electrical, structural, mechanical, and thermal properties.The polymerization process is not straightforward, and cannot be easily be performed without a full knowledge of the field of polymer synthesis. Indeed, a large number of contributing factors must be considered before attempting to synthesize copolymers, that include: (i) the type of monomers and compositions to be used; (ii) selection of the medium; (iii) the temperature of the synthesizing process; and (iv) the time required for synthesis to be completed. The problem persists however that, although excellent formulations can be prepared by optimizing the conditions of synthesis, the synthesized polymers may not possess all of the desired properties.Thus, the technique of polymer blending has been developed as a more convincing and practicable method to create high-performance polymer electrolytes membrane with known properties. Moreover, the polymer blends will possess
