Hydrophilic Crosslinked TEMPO-Methacrylate Copolymers - a Straight Forward Approach towards Aqueous Semi-Organic Batteries.

ABSTRACT: Crosslinked hydrophilic poly(2,2,6,6-tetramethylpiperidinyl-N-oxyl-co-[2-(methacryloyloxy)-ethyl]trimethyl ammonium chloride) [poly(TEMPO-co-METAC)] polymers with different monomer ratios are synthesized and characterized regarding a utilization as electrode material in organic batteries. These polymers can be synthesized rapidly utilizing commercial starting materials and reveal an increased hydrophilicity compared to the state-of-the-art poly(2,2,6,6-tetramethylpiperidinyl-N-oxyl-4-methacrylate) (PTMA). By increasing the hydrophilicity of the polymer, a preparation of cathode composites is enabled, which can be used for aqueous semi-organic batteries. Detailed battery testing confirms that the additional METAC groups do not impair the battery behavior while enabling straight-forward zinc
