▎ 摘　　要

NOVELTY - An electromagnetic shielding coating comprises 60-100 pts. wt. block copolymer, 40-60 pts. wt. graphene, 3-8 pts. wt. transition metal acetate, 1-5 pts. wt. anti-settling agent, 0.5-5 pts. wt. silane coupling agent, and 100-200 pts. wt. solvent. The graphene is monolayer graphene, double-layer graphene, few-layer graphene, and/or multilayer graphene. The transition metal acetate is ferrous acetate, and/or cobalt acetate. USE - Electromagnetic shielding coating for heat shrinkable tube. ADVANTAGE - The electromagnetic shielding coating does not fall off easily, and is prepared by simple process at low cost with high uniformity, conductivity, flexibility, and firmness, excellent heat shrinkage-proof property, wrinkle-resistance, and electromagnetic shielding effect, and less weight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of electromagnetic shielding coating for heat shrinkable tube, which involves adding block copolymer to solvent, uniformly mixing, adding anti-settling agent, dispersing, sequentially adding silane coupling agent, graphene, and transition metal acetate, and uniformly dispersing.
