| Abstract: |
| Electrostatic spray is an efficient and widely-used coating preparation technology. With the ability to produce fine particles and uniform spray distribution, it has shown a great potential in the processing and preparation of micro-nano materials. The new research progress of electrostatic spray technology in functionalized surface coating was introduced, and the advantages and disadvantages of electrostatic spray were summarized. In terms of electrostatic spray mechanism and device, the process of Taylor cone, fine jet and broken atomization was explained, and the growth process of the coating in the spray and the internal change after the accumulation were analyzed. The control methods of coating phase composition and crystal structure were discussed. The transmission of the droplets and the difference between the electrostatic field were introduced, and various devices and nozzle types including single nozzle, coaxial nozzle, multi-nozzle were compared. When it comes to the oxide coating, the formation conditions, the phase composition and the crystal structure of metal oxidation coating, non-metal oxide coating, metal particle doped oxide coating and the composite coating were summarized. Multiple functions of polymer coating were concluded. The application of electrostatic spray in sodium ion batteries, lithium ion batteries and perovskite solar cells was analyzed. The current research status of non-metallic inorganic coating containing carbon and silicon were described. The effects of electrostatic spray parameters on the structure of the coating and the relationship between the structure were discussed, and the thickness variation of the plurality of coating was summarized. Finally, the application and development trend of electrostatic spray technology were prospected. |
