NOVELTY - Preparing electromagnetic damage cloud of plasma with combustion type involves uniformly mixing 0.1-0.3mol of cobalt(II) chloride hexahydrate (CoCl2 6H2O) and 0.1-0.3mol of nickel chloride hexahydrate (NiCl2 6H2O) in 100 mL of ethylene glycol, magnetically stirring for 10-30 min to make it uniformly mixed; adding graphene the solution obtained, stirring until uniformly mixing, dropping hydrazine hydrate and 5-20 ml polyethylene glycol, putting in the reaction kettle at 160- 200 °C for 10-15 hours; adding carbon nano-tube into the mixed solution obtained, reacting for 2-5h at normal temperature, filtering, washing and dry the CoNi/graphene carbon nano-tube ternary wave-absorbing composite material. USE - Method for preparing electromagnetic damage cloud of plasma with combustion type used for absorbing and shielding the electromagnetic wave of the target signal to realize the cloud damage to the enemy weapon equipment (claimed). DETAILED DESCRIPTION - Preparing electromagnetic damage cloud of plasma with combustion type involves uniformly mixing 0.1-0.3mol of cobalt(II) chloride hexahydrate (CoCl2 6H2O) and 0.1-0.3mol of nickel chloride hexahydrate (NiCl2 6H2O) in 100 mL of ethylene glycol, magnetically stirring for 10-30 min to make it uniformly mixed; adding graphene the solution obtained, stirring until uniformly mixing, dropping hydrazine hydrate and 5-20 ml polyethylene glycol, putting in the reaction kettle at 160- 200 °C for 10-15 hours; adding carbon nano-tube into the mixed solution obtained, reacting for 2-5h at normal temperature, filtering, washing and dry the CoNi/graphene carbon nano-tube ternary wave-absorbing composite material. The squama-shaped phthalic anhydride is grinded into micron-sized powder by a ball mill at a rotating speed of 300r/min after dry in the drying box and then the ternary wave-absorbing composite material, phthalic anhydride powder, epoxy resin, aluminum powder, magnesium powder are mixed, the boron powder and the polytetrafluoroethylene are added into a ball mill to mix for 3 hours at a rotating speed of 50 r/min to obtain a uniformly distributed mixture. The mixture obtained is placed under the condition of 80-100 ℃, dried for 2-3h, put into the fuming tank to ignite to obtain plasma electromagnetic interference cloud group.
