▎ 摘　　要

NOVELTY - The method involves adopting a chemical vapor deposition method to prepare a graphene film. A vacuum filtration method is adopted to compound the graphene film and the purple phosphorus alkene to form a heterojunction. An electrode is prepared on the heterojunction graphene film to obtain the purple phosphorus alkene/graphene temperature-sensitive sensor. The purple phosphorus block is prepared into the purple phosphorus alkene by an ultrasonic method or a laser lift-off method. The purple phosphorus block is prepared by a chemical vapor phase transfer method. The content of the purple phosphorus alkene in the heterojunction is 0.25-0.75 mg. USE - Method for preparing violet-phosphorus alkene/graphene temperature-sensitive sensor (claimed) used in electronic information sensing field. ADVANTAGE - The purple-phosphorus alkene/graphene temperature-sensitive sensor provides high temperature sensitivity which can quickly and efficiently realize the response of the temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a purple phosphorus alkene/graphene temperature sensitive sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a purple phosphorus alkenyl thermo-sensitive sensor.
