چکیده
Highly sensitive smart sensors for early fire detection with remote warning capabilities are urgently required to improve the safety of combustible materials in diverse applications. The highly-sensitive alarm can detect situation within a short time quickly when disaster is about occur, which conducive achieve tuned. Herein, novel designed by using flame-retardant cellulose paper loaded graphene oxide (GO) and two-dimensional titanium carbide (Ti3C2, MXene). Owing excellent temperature dependent electrical resistance switching effect GO, it acts as an insulator at room becomes electrically conductive high temperature. During incident, partial oxygen-containing groups on GO will undergo complete removal, results conductivity transformation.Besides use feature, this work also introduces MXene enhance speed low temperature, especially below 300 {\deg}C. enough showing response 2 s 250 {\deg}C, calculated quantifiable technique. More importantly, sensor coupled wireless communication interface conveniently transmit signal remotely. Therefore, abnormal detected, wirelessly transmitted liquid crystal display (LCD) screen displays message such "FIRE DANGER". promising wallpaper interior house decoration other applications requiring warning.
