Researchers at Zhejiang University in China have developed a new aerogel-based material to create protection from the cold. They were inspired by the structure of polar bear fur, in which the hairs are hollow on the inside and have a strong protection on the outside. Each of them is a kind of insulating block, and at the same time provides physical protection for the skin from mechanical damage.
To give aerogel similar properties, Chinese scientists found a way to make encapsulated fiber. To do this, they froze the original material in rotation to turn it into a sol-gel. The resulting substance was subjected to freeze-drying and then applied an external semi-rigid coating.
