▎ 摘　　要

NOVELTY - Modified oxidized graphene film is adopting an evaporation-induced self-assembly method, organic molecules are introduced between the graphene oxide layers, and preparing modified oxidized graphene film. USE - Modified oxidized graphene film (claimed), for applying to the field of a fire alarm. ADVANTAGE - The film has high sensitivity, and strong thermal stability, is simple and low-cost, has high efficiency, is easy to popularize, and is suitable for mass production. DETAILED DESCRIPTION - INDEPENDENT CLAIM are included for: 1. a method for preparing modified oxidized graphene film, which involves using an improved Hummers' method to synthesize pure solid graphite oxide GO for future use, using physical crushing to obtain an organic molecular solution with floccule for future use, adding the solid oxide graphite GO into the water, using the GO dispersion liquid obtained by ultrasonic by the cell crushing instrument for future use, mixing GO dispersion with organic molecular solution, continuously stirring under the ultrasonic treatment to obtain the mixed dispersion liquid for further use, and pouring the mixed dispersion liquid after ultrasonic treatment into the polytetrafluoroethylene culture dish, drying in the drying box to obtain the modified oxidized graphene film; and 2. an application of modified oxidized graphene film, which comprises applying to the field of a fire alarm.
