Description
Summary:Recent research efforts in the field of electromagnetic interference shielding (EMI) materials have focused on biomass as a green and sustainable resource. More specifically, wood and cellulose nano fiber (CNF) have many advantages, some of which include lightweight, porosity, widespread availability, low cost, and easy processing. These favorable properties have led researchers to consider these types of biomass as an EMI shielding material with great potential. At present, while many excellent published works in EMI shielding materials have investigated wood and CNF, this research area is still new, compared with non-biomass EMI shielding materials. More specifically, there is still a lack of in-depth research and summary on the preparation process, pore structure regulation, component optimization, and other factors affecting the EMI shielding of wood and CNF based EMI shielding materials. Thus, this review paper presents a comprehensive summary of recent research on wood and CNF based EMI shielding materials in recent three years in terms of the preparation methods, material structure design, component synergy, and EMI mechanism, and a forward future perspective for existing problems, challenges, and development trend. The ultimate goal is to provide a comprehensive and informative reference for the further development and exploration of biomass EMI shielding materials.
