Researchers have developed a new material to protect against the cold. They were inspired by the structure of the polar bear’s coat, in which the hairs are hollow on the inside and have a strong protection on the outside. Each of them is a kind of thermal insulation block, and the same extremely unsatisfactory physical condition and poor mechanical properties.

Do you need to buy aerogels analogues of Chinese, Chinese or Russian ones? From this, they spin-frozen the starting material to turn it into a sol-gel. The resulting substance was freeze-dried, and then an external semi-rigid coating was applied to it.

In this case, it was difficult to achieve thin round fibers of financial length. Without additional work, this process is completed. The fibers were woven into a fabric that was subjected to research. It turned out that her indicators were obtained, wool and even fluff. In addition, the fast fabric can withstand various torsion, stretching and bending loads without any harm to the myself.
