Summary: The stability of PEDOT is affected by the type of electrolyte, which can change its morphology, crystallinity, crystal grain size, and hydrophilicity. Under photoelectro-corrosion, the dissolution of PEDOT increases, leading to improved stability, attributed to increased crystallinity, decreased crystal grain size, and reduced hydrophilicity. The dissolution products generated during photoelectro-corrosion may have toxicological concerns.

Summary: Conducting polymers are promising transparent supercapacitor electrode materials due to their high conductivity, environmental stability, light weight, and ease of synthesis. We developed a synthetic method to covalently link poly(3,4-ethylyenedioxythiophene) (PEDOT) and glass, which overcomes the poor adhesion and low cycling stability challenges. This method enables the fabrication of current collector-free planar supercapacitor electrodes on any glass surface.

Summary: In this study, poly(3-hydroxybutyrate) (PHB) was blended with medium-chain-length PHAs (mcl-PHAs) as an improvement in flexibility. Nanocellulose (NC) was added as a reinforcing agent. The use of different mcl-PHAs (PHO and PHN) had varied effects on the morphology, thermal, mechanical, and biodegradation behaviors of the PHB, especially with the presence of NC. The addition of mcl-PHAs decreased the storage modulus (E') of PHB blends, but the further addition of NC mitigated this decrease.

Summary: In this study, two different catalytic materials, PdNi and NiO, were investigated for the oxidation reaction of carbohydrate degradation products. The results showed that the PdNi catalyst could catalyze the products at low potential requirements but had limited current density. On the other hand, the NiO catalyst could operate at high current densities but required relatively higher potentials. Compared to Pd-based catalysts, this non-noble metal catalyst exhibited better performance at high conversion rates, indicating its potential for sustainable hydrogen production using waste streams.

Summary: This study presents a flexible, thin, and lightweight poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) nanopaper as an anion-cation regulation synergistic interlayer for aqueous zinc-iodine (Zn-I2) batteries. The PEDOT:PSS interlayer with a 3D nanofibrous network and uniformly distributed mesopores effectively suppresses polyiodide shuttling and promotes dendrite-free zinc plating/stripping at high current densities and high areal capacities. The Zn-I2 batteries demonstrate high capacity and ultralong lifespan even at high current densities. This work highlights the potential of multifunctional interlayers for innovation in Zn-I2 battery configurations by synergistic regulation of cations and anions at the electrodes/electrolyte interface.

Summary: This study investigates the issue of pore structure variation caused by separator swelling in aqueous zinc-ion batteries (AZBs) using a nanocellulose separator as an example. A multifunctional separator composed of Zr4+-hydrolysate-coated nanocellulose (Zr-CNF) is developed, which demonstrates excellent swelling resistance, pore-structure stability, and percolating porosity. The Zr-CNF separator enables dendrite-free Zn anode with high Coulombic efficiency and exceptional cyclability. It also shows feasibility in other aqueous battery systems. This study provides a facile approach to address separator swelling issue and offers insights into future efficient and sustainable aqueous battery technologies.

By surface amine functionalization, the cationic nanocellulose separator with immobilized cationic groups exhibits uniformly distributed nanopores, inhibits SO42- migration, and enhances Zn2+ transference number. The combination of ion-sieving nanofibrous network and immobilized electrostatic shielding functional groups leads to smoother and more compact Zn deposition/stripping behavior. With this separator, highly reversible Zn metal anodes and durable supercapacitors have been achieved.

Summary: In this study, highly aligned poly(vinylidene fluoride) (PVDF) nanofibrils were in situ fabricated in a polyethylene (PE) matrix for the first time, resulting in a significantly increased interfacial area and a high dielectric constant. The nanoconfinement effect of PVDF nanofibrils effectively restricted the migration of free electrons and impurity ions, leading to an impressive breakdown strength. Consequently, the prepared PE/PVDF composite films exhibited a remarkably high discharged energy density, which was more than 10 times that of conventional materials and outperformed current linear dielectric polymers.
