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
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.
