The thermal metamaterials market has huge development prospects, and related research and applications are still in the experimental stage.

Thermal metamaterials, also known as Thermal metamaterials, refer to composite structural materials that have artificially designed structures and can control heat conduction, convection and radiation in novel ways, thereby achieving extraordinary physical properties that natural materials do not have. They are a new category of metamaterials. one.

Metamaterials are a type of artificially manufactured advanced structural materials. They first started in the 1990s and first achieved rapid development in the fields of electromagnetics and optics. Since then, as research continues to deepen, the concept of metamaterials has gradually expanded to Acoustics, elastic waves, seismic waves, mechanics and other fields, and have achieved relevant advanced research and development results. As an expansion of metamaterials in the thermal field, the development of thermal metamaterials is relatively lagging behind, and relevant research only appeared in 2008.

According to the “Research Report on Market Monitoring and Future Development Prospects of China’s Thermal Metamaterials Industry from 2023 to 2027” released by the Industrial Research Center It shows that thermal metamaterials have powerful heat flow manipulation capabilities, and a variety of promising thermal metadevices can be designed using such materials, such as thermal concentrators, thermal rotators, thermal invisibility cloaks, thermal crystals, and thermal diodes. , zero energy consumption insulation, etc., the market shows great development prospects.

Specifically, in terms of thermal concentrators, thermal concentrators made of thermal metamaterials can greatly improve energy conversion efficiency and have higher application advantages in the thermoelectric effect. The terminal fields include energy, electronics, medical care, etc.; in In terms of thermal rotators, thermal rotators made of thermal metamaterials have higher application advantages in the field of thermal power; in terms of thermal invisibility cloaks, thermal cloaks made of thermal metamaterials have excellent temperature stealth functions and can perfectly Avoiding infrared detection has higher application advantages in the field of national defense and military.

The technical barriers to thermal metamaterials are high. Currently, related research and applications are still in the experimental stage globally. However, the excellent performance of thermal metamaterials has made them a key research area for institutions and enterprises in various countries. In the future, thermal metamaterials are expected to be widely used in the national defense and military fields by virtue of their superior properties, and the industry has huge development potential.

At this stage, the institutions in my country that have developed thermal metamaterials research and development tracks mainly include Huazhong University of Science and Technology, Fudan University, Northwestern Polytechnical University, Institute of Physics, Chinese Academy of Sciences, Southwest University, etc. In the future, as research gradually deepens, more advanced research and development results of thermal metamaterials will appear in China, and their industrialization process is expected to continue to accelerate.

Industry analysts said that thermal metamaterials are a type of advanced artificially designed structural composite materials in the field of thermal science. With powerful heat flow manipulation capabilities and unique diffusion engineering propagation methods, it can design a variety of promising thermal meta-devices, showing great development prospects in the fields of energy, electronics, military industry, medical care and other fields. However, due to technical limitations, the current research and application of thermal metamaterials are still in the experimental stage. In the future, R&D institutions and enterprises will need to speed up product research and development, thereby continuing to accelerate their industrialization process.
