| Zusammenfassung: | The invention discloses a cellulose-based biomass material containing 5-40 parts by mass of a cellulose-based biomass material with hydroxyl and carboxyl on the surface, 1-3 parts by mass of a macromolecular cross-linking agent, 5-20 parts by mass of carbon nanotubes and 40-90 parts by mass of a micromolecular solvent. The mass fraction is calculated relative to the overall mass of the high-performance bionic electromagnetic shielding coating material; and the high-performance electromagnetic shielding coating material has a three-dimensional electromagnetic shielding network structure formed by crosslinking the cellulose-based biomass material with hydroxyl and carboxyl on the surface and the carbon nanotubes through a macromolecular crosslinking agent. The obtained high-performance electromagnetic shielding coating material has good constructability, rheological property and high electromagnetic shielding performance, can be coated on various substrates through spraying, brushing and other modes, effectivel |
