“…The device fabricated with the above gel electrolyte resulted in a remarkable hike in the capacitance of about 129% compared to the device using a KOH aqueous electrolyte. In another work, Hou et al 235 incorporated hyperbranched poly(amine ester) nano-silica (HBPAESiO 2 ) into PVA/KOH gel electrolyte, increasing ionic conductivity, also producing an excellent electrode–electrolyte interface. The application of this electrolyte resulted in a significant increase in conductivity (7.09 mS cm −1 ) compared to that in PVA/KOH electrolyte (1.32 mS cm −1 ), which was for the hydrolysis of the ester groups by KOH to generate carboxylate salt moieties.…”

“…The electrolytic salts and plasticizers are absorbed in the polymer matrices, preventing the leakage of the liquid electrolytes. The polymer matrices include polyvinyl alcohol (PVA), [206][207][208][209] polyoxyethylene (PEO), [210][211][212] polyacrylamide (PAM), 213,214 poly(methylmethacrylate) (PMMA), 215,216 poly(amineester) (PAE), 217,218 and poly(vinylidene fluoride) (PVDF). [219][220][221] These single and multicomponent polymeric hosts provided good flexibility and stretchability for SCs used in wearable and portable devices.…”

In the past few years, supercapacitors (SCs) have attracted great attention in both academic and industrial sectors due to their high energy storage efficiency, reliable stability, and eco‐friendly process. Flexible solid‐state SCs as one of the ongoing focuses for the development of wearable and portable electronics have become the most promising energy storage devices for the smart power system due to their high power density, fast electrochemical response, high efficiency on the charge‐discharge process, and excellent electrochemical stability. In this study, the recent progress in the electrodes and electrolytes used for approaching high‐performance of the all‐solid‐state flexible SCs is reviewed. We first introduce basic operational principles of various SCs. And then we overview the electrode materials including carbon materials, conducting polymers, transition metal oxides/chalcogenides/nitrides, MXenes, metal‐organic frameworks, covalent‐organic frameworks, and the polymer‐based solid‐state electrolytes in different systems. Afterward, we summarize recent progress in the development of the all‐solid‐state flexible SCs and outlook for future research directions.

“…The development of emerging flexible electronics industry now requires a material to have many different properties including high permittivity, optical transparency, and flexibility for future technologies. − Polymer composite provides a potential material solution for these properties by composing a polymer matrix and reinforcing agents since a single material can hardly meet so many needs. The leveraged attributes from each of the constituents can be used to strengthen material properties.…”

Multifarious wearable electronics with flexible touch screens have been invented for extensive outdoor activities. One challenge associated with these wearable electronics is the development of materials with both high dielectric permittivity and anisotropic light transmission, which is responsible for high touch sensitivity and screen peep-proof protection, respectively. Herein, we demonstrated a scalable approach for assembling and aligning anisotropic cellulose in a polymer matrix through the thickness direction via the assistance of an electric field to address this challenge. The alignment of silver-coated fibrillated celluloses in the polymer matrix not only significantly increases dielectric permittivity but also effectively enhances optical anisotropy. The impact of alignment degree and filler content on the dielectric and optical properties of polymer composite films has been systematically studied. The kinetics and aligning mechanisms of silver-coated fibrillated celluloses are revealed by in situ optical microscope images while an electric field is applied. We believe that this study provides a facile strategy to enhance both dielectric permittivity and optical anisotropy of polymer composite films by the alignment of embedding nanoparticles via an AC electric field, which is essential for future flexible electronics and display technology.
