▎ 摘　　要

NOVELTY - Preparing biological degradable electromagnetic shielding coating comprises (i) taking 25-50 wt.% active ingredients and 50-75 wt.% low molecular solvent, where the active ingredients comprising 50-95 pts. wt. natural bio-based macromolecules, 3-50 pts. wt. conductive fillers and 0.5-2 pts. wt. auxiliary dispersants; (ii) adding natural bio-based polymers and conductive fillers into low molecular weight solvent, stirring and mixing to obtain a mixed solution; (iii) adding the auxiliary dispersant into the mixed solution, stirring continuously for 0.5-2 hours and vacuumizing to remove bubbles; and (iv) heating the mixed solution at 100-120degrees Celsius to volatilize the low-molecular-weight solvent, and concentrating to a solid content of 15-25%. USE - The method is useful for preparing biological degradable electromagnetic shielding coating is useful in human body wearing protection. ADVANTAGE - The method: prepares biological degradable electromagnetic shielding coating with good electromagnetic shielding efficacy; utilizes readily available the raw material; provides short process flow; and is easy to operate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a biological degradable electromagnetic shielding coating
