Nano metal leaf and preparation method thereof

The present invention discloses a method for preparing nano metal and leaves. The present invention uses pure form, morphology and size of the nano metal particles with controlled surface modifying agent having two or more reactive functional groups are dispersed in a polar organic solvent in the reaction mixture, after reaction at room temperature by the metal nano skeleton, the radial dimension of several microns, and the thickness of only several tens of nanometers, nano-metal leaf having a layered structure. The present invention is by mixing different polar solvent, to which a particular surface modifying agent, adjusting the nano metal crystals decompose and self-assembly process, the next step to prepare a nano metal leaf at room temperature, the obtained homogeneous product size, controllable high yield, dispersibility in a polar inorganic solvent is good, the reaction conditions are easily controlled, and can be mass produced.
