Comparatively, bulk ice has the highest elasticity of 0.3% and is rigid and fragile. The ultralow pressure in high vacuum and tensile stress under e-beam radiation also lowers the TN of the fiber. The extraordinary elasticity demonstrates the coupling effect of multiple fields on the mechanical and thermal properties of the fiber. The fiber has a considerable volume of supersolid skin wrapping the fiber. High vacuum conditions, e-beam radiation, mechanical tension, and molecular undercoordination enhance one another to relax and polarize the HB, making the fiber more elastic and flexible. Furthermore, water droplets confined within a hydrophobic pore or thin water films deposited on dielectric surfaces behave more like ice than liquid water at room temperature . A water droplet can travel through a microchannel much faster than classical fluid theory would predict , while an air gap stays between the skin of the droplet and the wall. The hydrophobic contact creates a 3.8 Å thick skin of 0.71 g/cm³ density, in addition to a 0.6 nm air gap between the SiO₂ wall and the fluid .
