Wallpaper tends to be highly flammable and can be a major contributor to house fires. But researchers at Shanghai’s Institute of Ceramics are developing wallpaper that can detect fire and even act as a flame retardant.
The wallpaper is made from fire-resistant materials like graphene oxide and hydroxyapatite nanowires. Graphene is electrically insulated and can be used like a sensor switch. When heat rises above a certain temperature, it will close a circuit and activate an alarm.
And just like commercial wallpaper, it will come in a variety of prints and colors.
“A smart fire-resistant and fire alarm wallpaper will be very desirable if it can simultaneously prevent the fire from spreading and send out alerts in a fire disaster,” the researchers write in their study
in the journal ACS Nano.
