Problems solved by technology

[0004] In short, the traditional light-to-heat conversion materials developed in my country have technical defects such as low light-to-heat conversion efficiency and poor heat storage durability.
However, most of the reports on new photothermal conversion materials at home and abroad focus on the application in biomedicine such as photothermal therapy, which is expensive and has not been applied in practical production.

Embodiment 1

[0031] Take a 200ml small beaker, put into it in turn: 50g oily acrylic resin, 2g absorbent, 30g xylene, 2.5g HP-731 water-based dispersant, 0.5g HP-512 silicone defoamer, HP-868 silicone Ketone leveling agent 0.5g, PN-700 high-performance adhesion promoter 3g, after continuous mechanical stirring to disperse evenly, apply it to the inner wall surface of the plexiglass box of 8 cubic centimeters by spraying, and place it at room temperature 2 days to allow the coating to cure naturally. The photothermal effect test was carried out under the condition of an ambient temperature of 20°C, and the test results are shown in image 3 with table 1. The absorbing agent is the CuS semiconductor nanoparticle with super nanometer microstructure prepared by the above method.
