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: To achieve high operating voltage and enhanced capacitance, a nanoscale dielectric layer is grafted onto a graphene electrode in this study, resulting in a dielectric-enhanced supercapacitor (DESC) that shows a higher capacitance by 2200% compared to a supercapacitor without dielectric grafting. The capacitance enhancement can be attributed to dielectric polarization, ions desolvation by the dielectric, and enhanced quantum capacitance from charge transfer and ion adsorption in the polymer molecules. A pouch DESC with a 1 M KCl electrolyte is confirmed to cycle up to 50,000 times with a capacitance retention of 87.5%. The optimal electrochemical properties of the DESC are achieved after grafting a 5 nm dielectric layer, providing new insights into the design of high-voltage and high-energy-density aqueous supercapacitors.

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.
