Composition-engineered graphene oxide-based fire warning research: A systematic review and new insight

Fire-warning systems (FWSs) attract increasing attention due to their potential for highly-efficient fire management, which have made some significant progress recently. Graphene oxide (GO) is one of the prime candidates on account of the insulate-to-conductive transformation under high temperature attack, it is precisely the electrical transformation can be captured for serving as a warning response. In this review, composition-engineered GO-based FWSs are reasonably sorted out and comprehensive analyzed, which constitutes a significant segment of FWSs research. Specifically, the evaluation covers the diversity of fabrication methods, variety of composition-engineered GO-based FWSs, the core fire-warning performance, as well as the relevant working mechanisms, etc . Furthermore, given the state-of-the-art in composition-engineered GO-based FWSs, the present challenge and the emerging perspectives are proposed, providing a guidance for tackling the main issues and promising developing direction of the next-generation of composition-engineered GO-based FWSs.
