Efficient Flame Detection and Early Warning Sensors on Combustible Materials Using Hierarchical Graphene Oxide/Silicone Coatings
The flammability of the combustible materials, such as polymer foams, woods, and textiles, has initiated massive fire accidents which cause not only considerable property loss and medical costs worldwide every year1 but also detrimental impact on the surrounding environment and global climate.2,3 The main drawback of smoke detectors and infrared heat detectors is that they are triggered in postcombustion and thus protractedly reflect the fire behaviors of materials, which cannot offer a timely and effective alarm signal to reduce or avoid the life and property loss in fire accidents.Therefore, a critical challenge is to develop efficient fire detecting/warning sensors that can trigger rapidly and reliably real-time signals once the combustible materials are attacked by a flame or even activate early warning signals in precombustion when they are encountering high fire risk, such as heat flux or abnormal high temperature for ignition.Advanced multifunctional sensors that can meet the requirement of extraordinary rapid and reliable responses for detecting high fire risk of combustible materials are strongly needed.
