Chinese researchers develop thermal fibers mimicking polar bear fur

HANGZHOU, Dec. 25 (Xinhua) -- Researchers in east China's Zhejiang Province have developed an ultra-warm, lightweight and durable aerogel fiber by mimicking the structure of polar bear fur.

Scientists from Zhejiang University's College of Chemical and Biological Engineering and the Department of Polymer Science and Engineering were involved in this research.

Polar bears have fur that has a porous core enc
