Synthesis of a TEMPO-Substituted Polyacrylamide Bearing a Sulfonate Sodium Pendant and Its Properties in an Organic Radical Battery

Abstract: A novel nitroxyl radical polymer poly(TEMPO-acrylamide-co-sodium styrene sulfonate) (abbreviated as poly(TAm-co-SSS)) was synthesized using 4-acrylamido-2,2,6,6tetramethylpiperidine (AATP) copolymerized with styrene sulfonate sodium (SSS). AATP was synthesized through a substitution reaction of acryloyl chloride. Meanwhile, poly(4-acrylamido-2,2,6,6-tetramethylpiperidine-1-nitroxyl radical) (PTAm) was prepared as a control sample. Then, the structures of products were characterized by nuclear magnetic resonanc… Show more

“…This is confirmed by the N 1s signal that is composed by two components with the same percentage peaked at 398.2 and 407.3 eV due to pyrrolic and N─O species. [ 35 ] Copper is present only as Cu(II), the pair of signals peaking at 934.4 eV (shakehand signal) and at 954.3 eV (shake up signal). [ 36 ] The position of the peaks suggests the presence of copper hydroxide like species.…”

“…Organic redox‐active compounds, such as stable nitroxide radicals and aromatic carbonyls, are considered as potential candidates for electrode active materials and alternatives to conventional inorganic metal oxides . For instance, aliphatic polymers containing 2,2,6,6‐tetramethylpiperidin‐1‐oxyl (TEMPO) as pendant group show fast and reversible charge/discharge reactions for 10 3 cycles as cathodes without memory effects . The fast electrochemical kinetics and electron self‐exchange reactions of TEMPO are important for the fast and reversible response .…”

“…As a result of that, PTMA has considerable application value in the application of high capacity density cathode materials for lithium batteries. [ 9–14 ] However, PTMA also has the defect of low theoretical capacity and poor conductivity, which limits its applicability. Therefore, scholars have also focused on the modification of PTMA to improve its conductive performance and capacity density.…”
