NOVELTY - The application claims a fabric structure polyimide fire alarm device. A polyimide of fabric structure, comprising: polyimide base; a first conductive layer, which is laminated on the polyimide body, and a second conductive layer, which is laminated on the first conductive layer; the first conductive layer is a graphene oxide layer, the second conductive layer is a carbon nano-tube layer or a boron nitride layer. The application is laminated on the polyimide body of the first conductive layer and the second conductive layer, the oxygen-containing group of the graphene layer is gradually removed under the condition of heating, so as to be reduced to conductive reduced graphene oxide layer, so that polyimide fabric structure is changed from non-conductive state to conductive state, after it is applied to the fire alarm circuit, it can quickly sense the occurrence of fire, eliminate the defect of manual fire alarm response hysteresis, has an ultra-fast response to the occurrence of the fire, plays a role of alarming in time. and the second conductive layer can strengthen the conductive or heat conduction, further accelerate the response sensitivity of the fire. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) the fabric structure polyimide to claim; (2) a fire alarm device.
