摘要
火灾预警系统的核心之一是新型传感材料。MXene及其衍生物具有较高的导电率和超大的比表面积、独特的温敏性及气敏性,可实现对早期火灾的快速可靠预警,因此,在火灾预警传感器领域具有广泛的应用前景。该文首先回顾了温敏型MXene基火灾预警器的预警机制及其纸类与涂层类器件在火灾预警领域的发展现状;随后,介绍了气敏型MXene基火灾预警器的预警机制及国内外近年来MXene及其衍生物在NH_(3)、NO_(2)、CO等气体检测的研究进展。重点总结了MXene在火灾预警领域高性能化、多功能化的发展趋势,并对MXene基火灾预警器后续发展趋势进行了展望。最后,指出未来MXene基火灾预警器应通过开发新型MXene基敏感材料以进一步缩短其响应触发时间、提高火灾预警的快速性与准确性,并考虑赋予器件自修复性、电磁屏蔽性、疏水性等多功能性,同时将其与物联网联动实现智能消防,使其更适合复杂环境和实际工程应用。
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.
