木基电磁屏蔽/吸波材料研究进展
Research Progress in Wood-based Electromagnetic Shielding/Absorbing Materials
摘要
Abstract
Electromagnetic shielding/absorbing materials have the ability to attenuate or absorb electromagnetic wave energy,and show great application potential in the fields of electronic equipment,biomedical engineering and national defense and security.Traditional metal-based materials have limited application due to their high density,complex processing processes and high costs,while carbon-based materials are also challenged in widespread application due to insufficient mechanical properties and low cost-effectiveness.Wood and its derivatives have been focused in the research on green and environmentally friendly electromagnetic shielding/absorbing materials,owing to their graded porous structure,low cost,easy processing and renewability.This paper reviews the mechanism of electromagnetic shielding and absorption,preparation processes(such as coating,filling and carbonization)and performance of wood-based materials.The potentials of these materials for broadband(between 1 and 40 GHz),lightweight and multifunctional applications are deeply explored.Maxwell-Wagner-Sellers interface polarization theory and waveguide model are used to clarify the structure-activity relationship between wood graded porous structure and electromagnetic attenuation,providing theoretical support for the development of high-performance wood-based electromagnetic shielding materials.关键词
