Scientists discover secret of ice-free polar-bear fur
This experiment showed that the ice adhesion of unwashed polar bear fur is exceptionally low. While the often-accepted threshold for “icephobicity” is around 100 kPa, the unwashed fur measured as little as 50 kPa. In contrast, the ice adhesion of washed (sebum-free) fur is much higher, coming in at least 100 kPa greater than the unwashed fur.
