基于纤维素纸的高灵敏度火灾报警系统，具有低温响应和无线信号转换
Highly sensitive fire alarm system based on cellulose paper with low temperature response and wireless signal conversion
摘要：
迫切需要具有远程报警功能的高灵敏度早期火灾检测智能传感器，以提高各种应用中可燃材料的防火安全性。高灵敏度的火灾报警器能够在火灾即将发生时，在短时间内迅速发现火情，有利于实现火灾调谐。在此，通过使用负载有氧化石墨烯（GO）和二维碳化钛（Ti3C2，MXene）的阻燃纤维素纸来设计新型火灾报警器。由于GO具有优异的温度依赖性电阻开关效应，其在室温下充当电绝缘体，并且在高温下变得导电。在火灾发生时，GO上的部分含氧基团会完全去除，导致导电性转变。除了使用GO特性外，本工作还引入了导电MXene，以提高低温（特别是低于300 °C）下的火灾探测速度和报警。设计的阻燃火灾报警器足够灵敏，可以检测到火灾事件，在250 °C下显示出2 s的响应时间，这是通过一种新颖的和可量化的技术计算的。更重要的是，设计的火灾报警传感器耦合到无线通信接口，方便远程传输火灾信号。因此，当检测到异常温度时，当显示诸如“火灾危险”的消息时，信号被无线地发送到液晶显示器（LCD）屏幕。所设计的智能火灾报警纸有望用作室内装饰和其他需要早期火灾检测和预警的应用的智能壁纸。
英文摘要：
Highly sensitive smart sensors for early fire detection with remote warning capabilities are urgently required to improve the fire safety of combustible materials in diverse applications. The highly-sensitive fire alarm can detect fire situation within a short time quickly when a fire disaster is about to occur, which is conducive to achieve fire tuned. Herein, a novel fire alarm is designed by using flame-retardant cellulose paper loaded with graphene oxide (GO) and two-dimensional titanium carbide (Ti3C2, MXene). Owing to the excellent temperature dependent electrical resistance switching effect of GO, it acts as an electrical insulator at room temperature and becomes electrically conductive at high temperature. During a fire incident, the partial oxygen-containing groups on GO will undergo complete removal, which results in the conductivity transformation.Besides the use of GO feature, this work also introduces conductive MXene to enhance fire detection speed and warning at low temperature, especially below 300 °C. The designed flame-retardant fire alarm is sensitive enough to detect fire incident, showing a response time of 2 s at 250 °C, which is calculated by a novel and quantifiable technique. More importantly, the designed fire alarm sensor is coupled to a wireless communication interface to conveniently transmit fire signal remotely. Therefore, when an abnormal temperature is detected, the signal is wirelessly transmitted to a liquid crystal display (LCD) screen when displays a message such as "FIRE DANGER". The designed smart fire alarm paper is promising for use as a smart wallpaper for interior house decoration and other applications requiring early fire detection and warning.
