Chinese scientists have developed an optical metamaterial fabric that can be passively cooled

Huazhong University of Science and Technology Wuhan Optoelectronics National Research Center Professor Tao Guangming’s research team, Professor Ma Yaoguang’s team from Zhejiang University, China Textile Science Research Institute Co.
, Ltd.
and many other units and interdisciplinary joint innovations have developed an optical metamaterial fabric that can be passively cooled.
The cooling effect is good, the wearable performance is high, and the application prospect is promising
.

After rigorous testing, under passive input conditions, metamaterial fabrics can achieve a cooling effect of 2°C-10°C lower than the ambient temperature throughout the day (Guangzhou, December 5-6, 2020)
.

Tao Guangming said that the research team combined optical metamaterial technology with batch fiber preparation technology, selected polylactic acid as the fiber raw material, and introduced new optical characteristics at specific wavelengths to obtain uniform and continuous metamaterial fibers
.

In addition, metamaterial fabrics also have the advantages of low cost, environmental protection, and industrialization, which are of great significance for realizing efficient outdoor personal thermal management, promoting the development and application of industrialization technology of smart textiles, and conforming to the global green and low-carbon development trend
