Abstract Fire early-warning sensors are crucial in fire monitoring. In this study, a sandwich-structured polyimide/graphene oxide flexible film sensor (PGP) was fabricated using a blade-coating method. This structural design not only imparts excellent mechanical properties to the PGP, but also enhances its thermal stability and flame retardancy through the synergistic effect between the protective role of the PI layers and the physical barrier function of the GO layer. The PGP exhibits high sensitivity to flames and demonstrates excellent thermoresistive response characteristics, with an early-warning response time of 750 ms and a sustained alarm signal lasting over 60 s. These features highlight its potential for applications in fire early-warning systems.

Key words： polyimide graphene oxide sandwich structure fire-warning response flame retardancy
