Abstract
Nanoparticles are atomic or molecular groups composed of a very small number of atoms or molecules. The particles have a shell structure. Nanomaterials are made up of a long-range ordered arrangement of atoms in grains and a disordered interface composition. The nanomaterial has a large number of interfaces. These unique volume effects, surface effects, and macroscopic quantum tunnelling effects enable nanomaterials to have unusual mechanical, electrical, magnetic, thermal, optical, catalysis, and superconducting properties. Such characteristics make nanomaterials have significant application value in the fields of national defense, electronics, chemical industry, metallurgy, light industry, aviation, ceramics, catalysts, medicine, etc. The development of nanomaterial technology will have a profound impact on the productivity and may solve a series of problems such as food, health, energy and environmental protection fundamentally. This article analyzes the application prospect of nanomaterial and different preparation method. At the same time, the advantages and disadvantages of preparation are shown in the article which provides a literature review for researchers to refer.
