Summary: In this paper, ternary DES (choline chloride, glycerol, Lewis acid) was used to pretreat lignocellulose, and the DES solution with dissolved lignin was utilized as the medium of hydrogel to prepare DES-based polyacrylic acid/polyvinyl alcohol (PAA/PVA) double network hydrogels with great mechanical properties, self-adhesion, and high electrochemical sensitivity. The hydrogels achieved a tensile strain of 400% and an elongation at break of 150 kPa due to the entanglement of PAA with PVA chains, the covalent linkage between Al3+ and PAA chains, and the metal phenol network (MPN) formed by Al3+ and lignin. Furthermore, the introduction of DES solution endowed the hydrogel with excellent electrical sensing ability and anti-freezing property, making it maintain good flexibility and ionic conductivity at -20 degrees C. The hydrogel also exhibited a high gauge factor of 4.19 as a flexible sensor, providing scientific ideas for the application of the pretreated DES solution in the field of flexible wearable.

Summary: In this study, we demonstrated the easy preparation of deep eutectic solvents (DESs) using various imidazolium iodides and iodine. The electrical conductivity of the DESs could be controlled by changing the mixture composition and imidazolium cation species. Especially, the DES composed of 1-ethyl-3-methylimidazolium iodide and iodine in a 1:4 molar ratio exhibited a high electrical conductivity of 70 mS cm-1, which was higher than that of the ionic liquid mixtures with iodine. The high electrical conductivity of DESs can be attributed to the Grotthuss mechanism in polyiodide based on viscosity results, Raman spectrum measurements, and quantum chemistry calculations.

Summary: Over the past few decades, the research on electrochromism has focused on altering the optical transmittance of electrochromic (EC) materials using a small applied voltage. Tungsten oxide (WO3) is commonly used in EC devices (ECDs) to achieve this effect. In this study, WO3 films were produced using a sol-gel spin-coating method, and the influence of various transparent conducting oxides (TCOs) on the construction of ECDs was investigated. The combination of fluorine-doped tin oxide (FTO) and indium-doped tin oxide (ITO) as the TCO and counter electrode, respectively, exhibited the highest coloration efficiency.
