Summary: Supercapacitors, known for their high power density, fast charging and discharging speeds, and long service life, are widely used in various fields. However, the integration of supercapacitors in flexible electronics faces challenges regarding extensibility, bending stability, and operability. To address these challenges, we deposited thiophene and 3-methylthiophene on patterned 304 stainless steel through electropolymerization to prepare stretchable conducting polymer electrodes. Moreover, the cycling stability of the electrodes was improved by protecting them with a poly(vinyl alcohol)/sulfuric acid gel electrolyte. The assembled flexible supercapacitors exhibited 93% stability even after 10,000 cycles of strain, highlighting their potential applications in flexible electronics.

Summary: This study explored conducting redox polymers (CRPs) as electrode materials for organic batteries, which are composed of a polypyrrole conducting polymer backbone with attached quinone pendant groups. A modular organic synthetic approach allowed for the assembly of pyrrole and quinone units into quinone-pyrrole dyads with tunable quinone formal potentials. By choosing CRPs with different quinone potentials as anode and cathode material, an all-organic water-based battery was constructed, showing good correlation between cell potentials and redox potential differences.

Summary: Through electrochemical polymerization of 3',4'-bis(alkyloxy)-2,2':5',2-terthiophene monomers on an ITO electrode, three multifunctional materials namely poly(3',4'-dibutoxy-2,2':5',2-terthiophene) (P1), poly(3',4'-bis(hexyloxy)-2,2':5',2-terthiophene) (P2), and poly(3',4'-bis(octyloxy)-2,2':5',2-terthiophene) (P3) were obtained. Cyclic voltammetry and spectroelectrochemical studies were conducted to investigate their characteristics. The modification of alkyl chain lengths did not significantly affect the band gap and color of the resulting polymers. Comparatively, P1 showed superior optical contrast and switching time values, making it a promising material for p-conjugated conducting polymers in the visible region. These derivatives of poly(3',4'-bis(alkyloxy)-2,2':5',2-terthiophene) demonstrated promising electrochromic properties and can be considered as next-generation multifunctional materials.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
