▎ 摘　　要

NOVELTY - The method involves preparing a graphene oxide solution to obtain an alcohol solution of graphene oxide at a predetermined ratio (S1). A local corrosion optical fiber is obtained (S2) by performing hydrofluoric acid chemical corrosion process. A partially corroded fiber is washed (S3) with deionized water. A graphene film layer is placed (S4) in a corroded portion of the locally corroded fiber to form a graphene oxide corrosion optical fiber. 1g weighing expanded Graphite is added into a flask container. 23 ml concentrated sulfuric acid is added to the flask container. Stirring and cooling processes are performed. USE - Method for manufacturing an evanescent wave-type humidity sensor. ADVANTAGE - The method enables meeting real-time humidity monitoring requirements. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an evanescent humidity sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for manufacturing an evanescent wave-type humidity sensor.
