Summary: The demand for high-speed communication at high frequency has led to the development of low-dielectric polymer films. Aromatic polyimide (PI) is commonly used in flexible circuit boards due to its excellent properties, but its dielectric constant is relatively high for high-frequency communication. To address this, a hyper-crosslinked polymer (HCP) was synthesized and blended with PI to form all-organic HCP/PI composite films. The porous structure of HCP helps to reduce the dielectric constant of the PI matrix. By adjusting the HCP content, the dielectric constant of the composite films can be effectively lowered in the desired frequency range. This method is simple and can be applied to other organic component-filled PI systems.

Summary: Cellulose-derived materials have gained attention in advanced electronics for their abundance, low cost, light weight, and sustainability. This study presents a paper-based triboelectric nano-generator (TENG) using sisal cellulose as the friction layer. The effects of surface morphology, structure, and dielectric properties of sisal cellulose paper (SCP) on the TENG's output performance were discussed. It was found that SCP-TENG's electrical output can be improved and controlled by chemically modifying SCP with different polar groups, and a chemical sensor for detecting the degree of group substitution was successfully fabricated.

Summary: Polymer film capacitors are important components for high-power applications, but their low energy density has made it difficult to meet the requirements of energy system miniaturization. Various strategies to improve the energy density of polymer dielectrics have been investigated, with particular interest in the construction of multilayer-structure composites. However, comprehensive and systematic reviews on the design principles and potential regulation mechanisms of multilayer interfaces are still lacking. This review summarizes recent progress in polymer-based multilayer-structure composite dielectrics, focusing on multilayer interface engineering and discussing various factors that affect their performance.

Summary: Surfactant-free, freestanding, and hierarchical two-dimensional polycrystalline cobalt oxide nanosheets with enriched oxygen vacancies (Co3O4-VO) were synthesized. These Co3O4-VO nanosheets outperformed the original nanosheets and conventionally calcined Co3O4 in electrochemical oxygen evolution and HMF oxidation to FDCA due to their preserved 2D structure and elimination of surfactant, exposing abundant active sites. The strain-induced oxygen vacancies at grain boundaries of Co3O4 nanocrystallines were also proposed to contribute to the improved electrooxidation performance. Furthermore, Co3O4-VO showed remarkable long-term stability in 1 M KOH chronoamperometric test.

Summary: The random mobility of charge carriers in g-C3N4 can lead to low photocatalytic efficiency. Controllable migration of charge carriers is proposed as a strategy to suppress charge recombination and facilitate charge separation. In this study, ethylenediamine modified g-C3N4 is found to exhibit improved photocatalytic activity, with enhanced charge separation being identified as a key contributing factor. TEM observation and DFT calculations reveal the accumulation of electrons on certain areas of the modified g-C3N4 surface. The introduction of -NH2 groups through modification significantly alters the electronic structure of g-C3N4, leading to the generation of midgap states that impact charge separation. This research offers a simple method to manage charge carrier migration and enable electron directional transfer, thereby suppressing recombination and enhancing photocatalytic activity.

Summary: Sodium metal anodes face challenges such as dendrite formation and poor reversibility due to inhomogeneous nucleation/growth and fragile solid electrolyte interphase (SEI). In this study, a dual-role crown ether additive (CEA) was introduced to improve the nucleation behavior and SEI features simultaneously. The CEA effectively regulated the desolvation kinetics to achieve uniform nucleation and growth of sodium, while also forming a NaF-rich SEI through the presence of Na+/CEA complexes. This approach resulted in stable cyclic stability for over 3000 hours, surpassing previous works.
