WASHINGTON, June 6 (Xinhua) -- Chinese scientists got inspiration from the hair of polar bears and developed a light-weight, stretchy heat insulation material, which can be applied in the architecture and aerospace sectors in the future.
The study published on Thursday in the journal Chem has shown that the insulator has a similar structure with the polar bear hair, which is hollow inside.
Under the microscope, a polar bear hair has a long, cylindrical cavity through its center that renders the bear remarkable heat-holding capacity, according to the study.
Scientists led by Yu Shuhong, a chemistry professor at the University of Science and Technology of China, produced a spaghetti-like aerogel block with millions of hollowed-out carbon tubes, each equivalent to a single strand of hair.
