Beijing (Web Desk): A group of Chinese scientist at the Shanghai Institute of Ceramics has invented the world's first fire-resistant and water-proof paper.
According to the scientist, the paper resists water even when its surface is physically damaged, and is unstained by liquids such as coffee and tea. It is also able to resist heat up to 200 degrees Celsius, making it fire-resistant.
The team said that it can also be wiped clean with water, without smudging what is written on it potentially offering a far more hardy archival material for documents to survive fire or water.
According to Professor Zhu Yingjie, the lead researcher on the project, this one is unique because it combines both properties while there are ways of making paper flame resistant or less susceptible to fluids.
Contrary to simple paper made of plant fibres, this one is made with hydroxyapatite nanowires which cannot be easily destroyed by any fluid.
Hydroxyapatite is a form of calcium found commonly in bone and teeth, and gives the paper its unique qualities.
Prof Zhu said, "Traditionally, paper is made of plant fibers, which are easily destroyed by liquid."
The paper is said to cost a "few yuan" more than the production cost of an equivalent A4 sized piece of paper, but the price might be reduced if it is mass manufactured.
