New Fabric Inspired by Polar Bear Hair

The thick pelt that helps polar bears to survive frigid Arctic winters has inspired a warm, sturdy fiber. Inspired by the microstructure and thermal insulation function of the polar bear hair, a research team led by Professor BAI Hao with ZJU’s College of Chemical and Biological Engineering has used a freeze-spinning technique to continuously fabricate silk fibroin solution into a fiber with aligned porous microstructure.
