“…By chemical and physical modification, it is possible to yield new polymer electrolytes with a broad range of functionalities designed to control transport properties. 1 Effective ion and charge transport through the electrolyte is needed to optimise energy conversion and storage in batteries, fuel cells, electrolysers or supercapacitors, 2 but the design of polymeric membranes is also crucial for other analytical and purification technologies. 3 The performance of some benchmark polymer electrolytes, however, depends on the presence of phase separated morphologies between polar and non-polar regions promoted by the presence of solvents, making it difficult to optimise the ion transport without altering other properties.…”

We have prepared a series of new ionically conducting polymer electrolytes consisting of side-chain liquid crystal terpolymers with mesogenic azobenzenes, sulfonic acid groups and methyl methacrylate. The poly[10-(4-methoxyazobenzene-4'-oxy)decyl methacrylate]-copoly[2-acrylamido-2-methyl-1-propanesulfonic acid]-co-poly[methyl methacrylate]s, 10-MeOAzB/AMPS/MMA terpolymers, were synthesised by a one-pot conventional radical polymerisation. All samples were characterised by NMR, GPC/SEC, FT-IR, POM, XRD, DSC, UV-visible spectrophotometry and EIS. The terpolymers have light responsive properties, and exhibit liquid crystallinity over a wide range of compositions. Above a certain threshold of AMPS content, the 10-MeOAzB/AMPS/MMA terpolymers exhibit ionic conductivities in the 10-8-10-4 S cm-1 range, with signs of decoupling of ionic mobility from segmental motions of the polymer.

“…The stable nitroxide present into the PTMA moiety presents a flat charge/discharge voltage profile at 3.6 V (vs. Li + /Li) with a theoretical capacity of 111 mAhg -1 . 8,[15][16][17][18][19][20][21] Moreover, by changing the surroundings of the nitroxide group e.g. 7,8 PTMA is usually produced by free radical polymerisation (FRP) of 2,2,6,6-tetramethylpiperidin-4-yl methacrylate (TMPM) followed by its oxidation into PTMA, and combined with conductive carbons and poly(vinylidene fluoride) (PVDF) to form the positive electrodes.…”

“…In this respect, a wide variety of polymers bearing stable radicals is now available. 8,[15][16][17][18][19][20][21] Moreover, by changing the surroundings of the nitroxide group, e.g. by adding an electron-withdrawing group next to it, it is also possible to stabilise the n-type redox pair between the nitroxide radical and the aminoxyl anion, giving an organic radical anode.…”

Nanostructured organic radical cathodes from self-assembled nitroxide-containing block copolymer thin films

This contribution describes the formation of nanostructured thin film organic radical cathodes. First, the self-assembly of poly(styrene)-block-poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) (PTMA-b-PS) diblock copolymers is detailed. In order to improve the nano-morphology of the immiscible PTMA and PS domains, the effect of thermal and solvent annealing is investigated. The formation of thin films with different morphologies such as cylindrical or lamellar nanostructures is observed depending on the processing conditions. The electrochemical properties of the nanostructured films are further investigated to assess the redox activity of the PTMA domains. Cyclic voltammetry of PTMA-b-PS diblock copolymers, either in dissolved or thin film supported configuration, confirms the reversible redox behavior of the nitroxide radical. Galvanostatic cycling of the thin film nanostructured cathodes reveals good capacity retention with fast charge/discharge response resulting from efficient charge and ion transfer as well as structural integrity. Such nanostructured organic radical cathodes provide opportunities for the fabrication of new generation nanostructured organic radical battery architectures.
