▎ 摘  要

NOVELTY - Preparing a nickel-ferrite base/water-based polyacrylate absorbing coating, comprises (i) preparation of aqueous polyacrylate emulsion; (ii) preparation of nickel ferrite/graphene oxide/polyaniline composite colloid; (iii) ultrasonically dispersing dispersant, aqueous polyacrylate emulsion, nickel ferrite/graphene oxide/polyaniline composite colloid and the curing agent in water to obtain a mixed material C; filtering the mixed material C, skimming the foam to obtain the nickel ferrite/graphene oxide/polyaniline aqueous polyacrylate coating; and (iv) washing and drying the substrate and fixing it; applying the nickel-ferrite/graphene oxide/polyaniline aqueous polyacrylate coating on the substrate, and curing. USE - The coating is useful in military and living square surface, communication, navigation, medicine and engineering. ADVANTAGE - The method solves the problem that the magnetic loss type wave-absorbing material and dielectric loss-type wave absorbing material in the background technology and bad dielectrically property.
