NOVELTY - Preparation of ferrocenyl-containing chiral poly Schiff base salts/graphene composite absorbing material involves using ferrocenecarboxaldehyde and anhydrous ethanol at ratio of 1 g/5 mL, taking ferrocenecarboxaldehyde, adding anhydrous ethanol, stirring to dissolve, heating to reflux to obtain ethanol-ferrocenecarboxaldehyde solution, dropwisely adding chiral(R)-1,2-propanediamine into ethanol-ferrocenecarboxaldehyde solution, stirring, refluxing under nitrogen atmosphere to obtain solution A, filtering, milling and thoroughly mixing with paraffin base. USE - Method for preparing ferrocenyl-containing chiral poly Schiff base salts/graphene composite absorbing material (claimed) used as wave-absorbing material, antistatic material and electromagnetic shielding material. ADVANTAGE - The method is simple. The product has excellent absorbing performance and large absorption strength and absorption band width. DETAILED DESCRIPTION - Preparation of ferrocenyl-containing chiral poly Schiff base salts/graphene composite absorbing material comprises: (A) using ferrocenecarboxaldehyde and anhydrous ethanol at ratio of 1 g/5 mL, taking ferrocenecarboxaldehyde, adding anhydrous ethanol, stirring to dissolve and heating to reflux at 50 degrees C to obtain ethanol-ferrocenecarboxaldehyde solution; (B) taking chiral(R)-1,2-propanediamine and ethanol at ratio of 1 g/10 ml, dropwisely adding chiral(R)-1,2-propanediamine into ethanol-ferrocenecarboxaldehyde solution at 50 degrees C for 30 minutes, stirring and refluxing for 5 hours under nitrogen atmosphere to obtain solution A; (C) filtering solution A and drying the resulting cake under vacuum at 40 degrees C for 12 hours to obtain ferrocene-based chiral bis Schiff base; (D) taking ferrocene-based chiral bis Schiff base and chloroform at ratio of 1 g/5 ml, dissolving ferrocene-based chiral bis Schiff base in chloroform and heating at 60 degrees C; (E) adding 1 g/2 ml chloroform solution of terephthaloyl chloride and 1 g/10 ml nitrobenzene solution of aluminum chloride to ferrocene-based chiral bis Schiff base solution, heating at 80 degrees C, stirring at reflux under nitrogen atmosphere for 24 hours to obtain solution B; (F) adding solution B in 1 g/1 ml aqueous solution of ferrous sulfate, stirring at reflux for 24 hours under nitrogen atmosphere, filtering under reduced pressure, successively washing the resulting cake with chloroform, washing with ethanol for 2-3 times and vacuum-drying for 12 hours to obtain ferrocenyl chiral poly Schiff base salts; (G) ultrasonically dispersing chiral ferrocenyl Schiff base salt in anhydrous ethanol to obtain ferrocenyl chiral poly Schiff base salts ethanol suspension and adding graphene to obtain ethanol-graphene dispersion; and (H) adding ferrocenyl chiral poly Schiff base salt suspension to ethanol-graphene dispersion, carrying out ultrasonic dispersion, filtering, drying cake at 40 degrees C for 12 hours, placing in ball mill, milling at speed of 150 revolutions/minute for 20 minutes and thoroughly mixing with paraffin base.
