Scientists have created such a 're-writable paper', which can be written multiple times and can be printed many times. The team making it claim that with its help paper consumption and pollution can be reduced. The special thing is that only a change in temperature can be erased and rewritten.
Professor Lujuo Chen of Fujian Normal University of China told that, "If most of the re-writeable paper is written, it is deleted in a few weeks or months, but the written on this paper will not be lost for at least 6 months."
So Chen and his team made this re-writeable paper together with three layers, just like a sandwich.
A side blue color diaper of this paper has been used which disappears when the heat grows. While the other side black toner has been used, which produces heat together with the light.
A special type of 'pen' has also been designed to write on this paper. This pen generates heat on paper and writes. Because this can only be written on paper when the temperature is high.
The team claims that this re-writeable paper is easy to make and it can be used in many places.

Paper is made up of three layers
The concept of re-writable paper is not new but due to its fabrication, ultra-violet light is needed to remove the content written on it or it needs energy to maintain it.So Chen and his team made this re-writeable paper together with three layers, just like a sandwich.
A side blue color diaper of this paper has been used which disappears when the heat grows. While the other side black toner has been used, which produces heat together with the light.
This way you can use it
This re-writable paper can be used by changing temperature. When the temperature exceeds 65 degrees Celsius, the color of this paper will turn white from blue and write it again. But when the temperature is below -10 degrees Celsius, it will again get blue color.A special type of 'pen' has also been designed to write on this paper. This pen generates heat on paper and writes. Because this can only be written on paper when the temperature is high.
Can use it many times
To re-use this paper, the temperature will be reduced to -10 degrees Celsius and the paper must be cooled so that the writing can be erased. The team making it claim that this paper can be used 100 times more often.The team claims that this re-writeable paper is easy to make and it can be used in many places.
