Scientists from the Shandong University in China developed a low-cost, environmentally friendly way to create printed materials with rewritable paper that can considerably reduce paper wastage. The new material is made out of tungsten oxide and a common polymer used in medicines and food.
The researchers created a film by mixing low-toxicity tungsten oxide with polyvinyl pyrrolidone. They exposed the material to ultraviolet light for 30 seconds or more, and it changed from white to a deep blue, this printing on it. Testing showed the material could be printed on and erased 40 times before the quality started to decline.
The study appears in the journal ACS Applied Materials & Interfaces.
