In China, scientists Pussenkova pedagogical University in China have developed the paper reusable.
Write on it with termorock or infrared light, the article says the American chemical society.
Your “writings” will be stored up to six months, but you can quickly get rid of just paper cooled to -10 degrees Celsius. Refrigerator help you.
The miracle material has three layers: in the middle is plain paper, the top thermochromic layer bottom — black photothermal toner. And provides latest paper “stirlin” opportunities.
At room temperature the paper has the blue color after heating (using termorock), the solvent becomes liquid, that colorautomatic and developer are distributed, and the paper becomes colourless.
The inscription on the paper can be erased by putting it in the fridge
