In an effort to reduce paper waste, researchers Ting Wang, Dairong Chen and colleagues from Shandong University in China have developed a rewritable paper made of tungsten oxide and a common polymer used in both medicines and food.
To “print” on the paper, the researchers exposed it to ultraviolet light for 30 seconds or more and to make pictures or words, they used a stencil to turn the exposed parts blue. Lastly, to speed up the process of erasing, the researchers used heat to make the color disappear in 30 minutes.
