Summary: Transition metal carbonitrides (MXene) have gained attention in the supercapacitor field due to their two-dimensional layered structure. However, their performance is affected by self-stacking. To address this issue, researchers used one-dimensional cellulose nanofibers (CNF) and carboxylic single-walled carbon nanotubes (SWCNT) to intercalate MXene, resulting in well-dispersed MXene/SWCNT/CNF aqueous suspensions and hybrid hydrogels. These hydrogels were then transformed into hybrid aerogels through supercritical drying. The CNF provided excellent porosity, high specific surface area (301.03 m2 g-1), good electrolyte infiltration, and mechanical flexibility, while the SWCNT contributed to high conductivity in the aerogel film. The researchers successfully assembled a symmetrical all-solid-state flexible supercapacitor and interdigitated micro-supercapacitors using the aerogel film as a flexible electrode, achieving area specific capacities of 746.68 mF cm-2 and 244.50 mF cm-2, respectively. This study presents a fabrication method for polymer-inorganic hybrid nanocomposite aerogel film electrodes for flexible supercapacitors.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
