Non-flammable paper does not burn

Researchers at the University of Arkansas at Fayetteville have developed a durable, fire-retardant, antimicrobial, reusable, and kill-resistant paper.

While most of the paper is made from cellulosic fibers, the new material is made of titanium dioxide nanowires, a chemical commonly found in white dyes.

"This basic material is simple, non-toxic and inexpensive," said Ryan Tian, assistant professor of chemistry and biochemistry at the university.

To make such nanofibers, first mix titanium dioxide with an alkaline solution and place it in a Teflon-coated container. They then heat the mixture on a furnace at 150 to 250 degrees Celsius for a few days. When the alkali evaporates, the remaining white, long fibers remain.

These nanofibers are washed in distilled water, and when still wet, they are poured into three-dimensional shapes such as tubes, bowls or cups. When the paper dries, it can be bent, folded or cut with scissors.

The final product can withstand temperatures up to 700 degrees Celsius, causing the flame to slow down.

The product may have many applications, from the manufacture of bacteria can be reused repeatedly, fire retardant wallpaper can automatically decompose toxic substances in the air, to the type of advertising banners Heat, can be rewritten along the highway.

The team has patented the process and is looking for partners to commercialize the product.
