Abstract

Abstract A recent research focus has been on developing sustainable and renewable high-performance electromagnetic shielding materials. We present here a robust and effective top-down method in which polydopamine (PDA) is added to delignified wood via in situ polymerization, and Ag particles are successfully deposited in the wood channel via PDA’s adhesive property with a subsequent silver mirror reaction. According to our findings, when the AgNO3 content is 30 g/L, the conductivity of 2-mm-thick conductive wood reached 500 S/cm with an electromagnetic interference shielding efficiency of 50 dB in the X-band. The three-dimensional network structure of the wood is preserved, and thus it has good mechanical properties. Hence, silver-plated wood can be used as an electromagnetic shielding material that requires high strength. Graphical Abstract

高导电性镀银多孔木材的制备

摘要最近的研究重点是开发可持续和可再生的高性能电磁屏蔽材料。我们提出了一种稳健有效的自上而下的方法，通过原位聚合将聚多巴胺（PDA）添加到脱木素木材中，并通过PDA的粘合性能成功地将Ag颗粒沉积在木材通道中，随后进行银镜反应。根据我们的发现，当AgNO3含量为30 g/L时，2毫米厚的导电木材的电导率达到500 S/cm，电磁干扰屏蔽效率为50 X波段为dB。木材的三维网状结构得以保留，因此具有良好的力学性能。因此，镀银木材可以用作要求高强度的电磁屏蔽材料。图形摘要

期刊介绍： The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization. JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
