摘要
The present invention relates to a method for manufacturing two-dimensional calcium carbonate nano-sheets and two-dimensional calcium carbonate nano-sheets obtained thereby. The method includes the steps of: preparing pearl powder; removing proteins contained in the pearl powder and forming slurry; irradiating microwaves to the slurry to obtain calcium carbonate powder; adding the calcium carbonate powder to a dispersion solvent to obtain a dispersion; irradiating ultrasonic waves to the dispersion to carry out exfoliation of the calcium carbonate powder; and isolating and recovering two-dimensional calcium carbonate nanosheets formed by exfoliation of the calcium carbonate powder. According to the method, it is possible to obtain two-dimensional calcium carbonate nano-sheets formed of a single layer having a thickness of about 1.2 nm.
