▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide aerogel wave-absorbing microspheres with chiral helical structure comprises (i) dissolving calcium chloride in a solvent to obtain a coagulation bath solution, where the concentration of the calcium chloride solution is 4-6 wt.%, (ii) adding the camphorsulfonic acid solution to the graphene oxide dispersion, and uniformly mixing to obtain a spinning solution, where the concentration of camphorsulfonic acid in the spinning solution is 0.8-1.2 mol/l and the concentration of graphene oxide 4-6 mg/ml, (iii) using the coagulation bath solution obtained in the step (i) as a droplet collector for wet spinning, (iv) restoring the graphene hydrogel collected in the coagulation bath solution obtained in the step (iii), (v) cleaning, freeze-drying, obtaining the desired camphorsulfonic acid-reduced graphene oxide aerogel absorbing microspheres to obtain graphene aerogel absorbing microspheres. USE - The microspheres is useful for microwave absorber (claimed). ADVANTAGE - The method: is simple; has convenient operation ; obtains aerogel absorbing microsphere having good electromagnetic wave absorption performance.
