Abstract: The core of fire warning system is new sensing materials. MXene and its derivatives, with high
electronic conductivity, large specific surface area, and unique temperature and gas sensitivity, could realize
fast and reliable early fire warning, which leads to their great application potential in early fire warning
sensors. Herein, the early warning mechanism of temperature-sensitive MXene-based fire alarms and the
status quo of paper type and coating layer type sensors were firstly reviewed, followed by summarization on
the early warning mechanism of gas-sensitive MXene-based fire alarms and the development status of
MXene and its derivatives in NH 3, NO 2, CO, and other gas detections with emphasis on the research progress
of MXene-based fire warning sensors in high-performance and multifunctional fire warning system.
Meanwhile, the future development trend of MXene-based fire warning sensors was also discussed, which
pointed out that the future MXene-based fire warning sensors should be optimized through new
MXene-based sensitive material development to reduce their response time, improve the rapidity and
accuracy, and explore device self-healing, electromagnetic shielding, hydrophobic and other multifunctional
features, and through linkage with the internet of things to achieve intelligent fire warning and further make
them more suitable to be used in complex environment and practical engineering field in the future.
