Abstract

With the acceleration of the miniaturization of electronic devices and the increasingly severe problem of electromagnetic pollution

it is crucial to develop electromagnetic shielding materials that possess both efficient shielding performance and good flexibility. Traditional metal-based shielding materials have limitations

such as heavy weight and poor flexibility. In contrast

hydrogels exhibit unique potential owing to their intrinsic flexibility

biocompatibility

and designability

thereby offering innovative paradigms for next-generation flexible electromagnetic shielding materials. This review first introduces the electromagnetic shielding mechanism of hydrogels and discusses the key factors affecting their shielding performance

including water molecules

porous structures

and types of conductive fillers. Second

it systematically explores the main methods for improving the electromagnetic shielding performance of hydrogels

including the use of different types of inorganic conductive fillers

the introduction of intrinsically conductive polymers

and rational structural design

and compares and analyzes the performance advantages and optimization strategies of various methods. Subsequently

it summarizes the practical applications of hydrogel-based electromagnetic shielding materials in flexible electronics and the research progress of stimulus-responsive intelligent shielding hydrogels. Finally

it looks forward to the current challenges and future development directions of hydrogel-based shielding materials.
