As a new preparation technology, micro and nano scale materials have significant differences in structure and properties from large scale materials. In the particle size, morphology and other characteristics change, electrical, optical, magnetic and other macro properties will also change, widely used in semiconductor, electronics, display, photothermal and functional materials and other high-tech fields.

According to the chemical composition, nanomaterials can be divided into nano-metal, nano-crystal, nano-ceramics, nano-glass, nano-polymer and nano-composite materials. According to the material properties, it can be divided into nano-semiconductor, nano-magnetic materials, nano-linear optical materials, nano-ferroelectrics, nano-superconducting materials, nano-thermoelectric materials, etc. According to the application field, it can be divided into nano-electronic materials, nano-photoelectric materials, nano-biomedical materials, nano-sensitive materials and nano-energy storage materials. Nanomaterials have five characteristics, such as volume effect, surface effect, quantum size effect, quantum tunneling effect and dielectric limiting effect, which have broad application prospects.

The preparation technology of micro and nano materials involves the purification of raw materials, the control of size and morphology, and has been the focus of technical research. Engineering technology includes raw material extraction and storage, transportation, temperature and pressure control, mixing, reaction aging, separation, purification, concentration, crystallization and drying processes. The separation technology generally adopts sedimentation, centrifugation, coarse filtration, fine filtration and membrane filtration.
