1、 Preparation process of carbon nanotube/acrylic ester coating

As a nanoscale material, the dispersibility and stability of carbon nanotubes are key factors in preparing high-quality coatings. Therefore, in the preparation process, we adopted advanced dispersion technology to ensure the uniform distribution of carbon nanotubes in the acrylic coating. Meanwhile, by optimizing the formula and process conditions, the high-performance and stability improvement of the coating have been achieved.

In the preparation process, we first chose high-quality carbon nanotubes and acrylic resin as raw materials. Then, the carbon nanotubes were uniformly dispersed in the acrylic resin through methods such as mechanical stirring and ultrasonic dispersion. Next, add an appropriate amount of additives and solvents to adjust the viscosity and flowability of the coating to meet the construction requirements. Finally, after filtering and packaging processes, high-performance carbon nanotube/acrylic coating was obtained.

2、 Exploration of Infrared Absorption Performance

Infrared absorption performance is one of the important indicators for measuring the performance of coatings. Carbon nanotubes excel in infrared absorption due to their unique conductivity and electromagnetic wave absorption properties. When carbon nanotubes are uniformly dispersed in acrylic coatings, they form an effective conductive network that can significantly enhance the infrared absorption capability of the coating.

In order to investigate the infrared absorption performance of carbon nanotube/acrylic ester coatings, we conducted a series of experiments and tests. Firstly, we prepared coating samples with different carbon nanotube contents and tested their infrared reflectivity and absorptivity. The experimental results show that with the increase of carbon nanotube content, the infrared absorption rate of the coating gradually increases, while the reflectivity decreases accordingly. This fully demonstrates the role of carbon nanotubes in enhancing the infrared absorption performance of coatings.

In addition, we also measured and analyzed the electromagnetic parameters of the coating. By comparing the changes in electromagnetic parameters of different samples, we found that the addition of carbon nanotubes not only improved the conductivity of the coating, but also enhanced its electromagnetic matching characteristics, thereby enhancing the infrared absorption effect of the coating.

Carbon nanotube/acrylic coating has broad application prospects in military stealth, thermal management, electromagnetic shielding and other fields due to its excellent infrared absorption performance. With the deepening of research and the advancement of technology, this coating is expected to achieve a wider range of applications in the future.
