Summary: The energy storage performances of supercapacitors can be improved by using nanostructured hierarchically micro/mesoporous hollow carbon materials, which have ultra-high specific surface areas and rapid diffusion of electrolyte ions. In this study, hollow carbon spheres were prepared by high-temperature carbonization of self-assembled fullerene-ethylenediamine hollow spheres. The obtained carbon spheres showed large surface areas and pore volumes, and exhibited remarkable electrochemical capacitance properties.

Summary: Discrete polymers are a valuable tool for studying chain structure, self-assembly behavior, and functional applications. However, the development of discrete polymers with self-immolative properties is limited. In this study, we synthesized a library of self-immolative oligourethanes through stepwise growth, which exhibited cascade depolymerization and selective cleavage properties. These oligourethanes also displayed different morphologies and morphological transitions in aqueous media and upon thermal annealing.

Summary: This study successfully achieves the controllable and reversible assembly of nanofibers from natural macromolecules through protonation and deprotonation. The size and morphology of the assembled nanostructures can be precisely controlled by manipulating the electrostatic interaction. The reversible assembly allows for dynamic reorganization of the nanostructure in response to environmental changes.

Summary: In this study, hollow-structured hydroxy vanadium oxide (VOOH) was constructed, and VOOH@MXene composite material was prepared through electrostatic self-assembly. The composites have effective attenuation and absorption of electromagnetic waves. The excellent conductivity of MXene compensates for the low conductivity of VOOH, and the hollow structure of VOOH prevents the stacking of MXene sheet layers and improves the impedance matching problem. The VOM_10 composite exhibits good microwave absorption performance with a minimum reflection loss of -34.9 dB and a maximum effective absorption bandwidth of 4.08 GHz. The preparation of VOOH@MXene composites using electrostatic self-assembly and the construction of a hollow structure provide a new idea for the study of lightweight and high-performance wave absorption materials.
