Polar bears inspire novel heat insulating material

Beijing, Jun 10 (PTI) Scientists have developed an insulator that mimics the structure of individual polar bear hairs and may have many real world applications in the architecture and aerospace sectors.

For polar bears, the insulation provided by their fat, skin, and fur is a matter of survival in the frigid Arctic.

For engineers, polar bear hair is a dream template for synthetic materials that might lock in heat just as well as the natural version.

"Polar bear hair has been evolutionarily optimised to help prevent heat loss in cold and humid conditions, which makes it an excellent model for a synthetic heat insulator," said Shu-Hong Yu, a professor at the University of Science and Technology of China (USTC).
