Effects of static magnetic field on optic properties of water are investigated by infrared spectroscopy, ultraviolet spectroscopy and X-ray diffraction, respectively. The ultraviolet spectroscopy experiments show the changes of properties of water under action of static magnetic field, in the region of 191 to 400 nm. The infrared experiment shows that the water exposed in a magnetic field had saturation and memory effects. The magnetized effects increased with increasing exposed time, but were weakened with increasing of time when the magnetic field was removed. In the X-ray experiment, the strength of diffraction increased also, after the water was exposed in magnetic field. Meanwhile, the shift of peak and increase of strength of X-ray diffraction of magnetized water added with nanoFe3O4 occurred as compared with that of pure water added with nano Fe3O4. This result suggests that the magnetized wa- ter has certain magnetism. Finally, these phenomena are simply explained by the molecular structure of water and the theory of magnetization of water. 展开更多

Ionic skins that demonstrate great advantages in the mechanical properties and multiple sensory capabilities are regarded as an attractive candidate to mimic functions of human skin.However,human skin is vulnerable to be damaged under long-time sunlight irradiation,and most of the current ionic skins also lack a protection against harmful ultraviolet and infrared lights.Herein,this work develops a multifunctional ionic skin based on ionic conductive and light-managing hydrogels via a facile one-step locally confined polymerization.It is mechanically adaptable,able to modulate light in the broadband solar spectrum,and protect human skin from the harmful ultraviolet and infrared lights.Moreover,without complicated processing,the ionic skin enables human-machine interactions via wireless and optical camouflaged Morse codes.We believe this work will promote the development of smart wearable devices with multiple customizable functions. 展开更多
