It is known that fossil fuels such as oil, natural gas and coal are non-renewable energy sources, and the combustion of these fossil fuels causes serious pollution to the environment. Therefore, it is necessary to replace fossil fuels with new energy, and solar energy is an inexhaustible green and environment-friendly energy, so that the research of converting solar energy into heat energy has important significance.
Among solar thermal technologies, concentrated solar technology is one of the most mature technologies, and solar absorptive coatings play an irreplaceable role in concentrated solar technology. The absorption effect of the solar energy absorption coating on sunlight directly influences the efficiency of converting solar energy into heat energy, so that the coating with high absorption rate on the sunlight in a wide waveband range is obtained. Until now, there have been many studies on solar absorptive coatings, but most of them are in the narrow band range (1000nm band) and can only reach absorption around 90%.
At present, the preparation method of the solar energy absorption coating mainly comprises the following steps: magnetron sputtering, electrochemical deposition, sol-gel, paint coating, high-voltage electrostatic spraying, etc. The high-voltage electrostatic spraying method has the advantages of low cost, simple operation, easily controlled conditions, uniform coating, large-scale production, high production efficiency and the like. The principle is that according to the physical phenomenon of electrophoresis, a coated object is used as an anode and is generally grounded, a coating atomizing mechanism is used as a cathode, and a negative high voltage is connected with a power supply, so that a high-voltage electrostatic field is formed at the two electrodes. Because corona discharge is generated at the cathode, the sprayed coating medium can be charged and further atomized. According to the principle of 'like charges repel and opposite charges' the charged coating medium is acted by an electric field force, and flows directionally to the surface of the object to be coated, which is positively charged, along the direction of the electric field under the action of the electric field force.
Therefore, it is of great significance to prepare an absorptive coating having a high absorption rate in a wide wavelength band by a simple method.
