High performance, durable polymers including poly(phenylene)
| DWPI Title: Composition for forming polymer used in proton exchange polymeric membranes, e.g. fuel cells or flow batteries, comprises poly(phenylene) structure or its salt |
| Abstract: The present invention relates to functionalized polymers including a poly(phenylene) structure. In some embodiments, the polymers and copolymers of the invention include a highly localized concentration of acidic moieties, which facilitate proton transport and conduction through networks formed from these polymers. In addition, the polymers can include functional moieties, such as electron-withdrawing moieties, to protect the polymeric backbone, thereby extending its durability. Such enhanced proton transport and durability can be beneficial for any high performance platform that employs proton exchange polymeric membranes, such as in fuel cells or flow batteries. |
| Use: The composition is useful for forming polymer (claimed) used in proton exchange polymeric membranes, e.g. fuel cells or flow batteries. |
| Advantage: The polymers and copolymers include a highly localized concentration of acidic moieties, which facilitate proton transport and conduction through networks formed from these polymers. In addition, the polymers can include functional moieties, such as electron-withdrawing moieties, to protect the polymeric backbone, thus extending its durability. Such enhanced proton transport and durability can be beneficial for any high performance platform that employs proton exchange polymeric membranes. When the polymer includes both hydrophilic and hydrophobic segments (e.g. such as in a copolymer), the ratio of these two segments can be controlled. Enhanced control, in part, can allow the user to tune this ratio, where the optimal ratio will minimize swelling of the polymer by water or another aqueous solvent. For instance, minimizing the hydrophilic segment will generally minimize swelling. |
| Novelty: Composition comprises poly(phenylene) structure or its salt. |
