Lightweight and Mechanically Robust Cellulosic Triboelectric Materials for Wearable Self-Powered Rehabilitation Training

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 2, 2025

Lightweight and robust self-powered wearable devices are of great importance in rehabilitation medical assistance, but this places greater demands on the development functional materials. In particular, a balance between reducing weight materials enhancing their mechanical performance is urgently needed. Here, study reports design strategy based cross-scale strengthening mechanism, which endows triboelectric with mechanically properties, can withstand more than 16,600 times its without any deformation. A biomimetic ordered network structure "wall-septum" obtained by using directional ice templating method, followed formation hydrogen bonds polymer molecular chains promoted salting-out. The resultant material exhibits Young's modulus 130.3 MPa, specific 409.0 kN m/kg. Triboelectric used to construct highly nanogenerators that stable even under an impact 735.5 kPa. accurate acquisition human motion state signal process training realized. This provides universal for lightweight solution application training.

Biopolymer‐Based Flame Retardants and Flame‐Retardant Materials

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Abstract Polymeric materials featuring excellent flame retardancy are essential for applications requiring high levels of fire safety, while those based on biopolymers highly favored due to their eco‐friendly nature, sustainable characteristics, and abundant availability. This review first outlines the pyrolysis behaviors biopolymers, with particular emphasis naturally occurring ones derived from non‐food sources such as cellulose, chitin/chitosan, alginate, lignin. Then, strategies chemical modifications flame‐retardant purposes through covalent, ionic, coordination bonds presented compared. The is placed advanced methods introducing biopolymer‐based retardants into polymeric matrices fabricating materials. Finally, challenges sustaining current momentum in utilization further discussed.
