▎ 摘　　要

NOVELTY - The method involves cleaning a surface of a silicon substrate to form a silicon dioxide layer. Electrostatic force is determined between first electrode and second electrode i.e. gold electrode. Concentration of the substrate is 0.2-2 mg/mL. The substrate is dipped into deionized water for rinsing for 1-30 minutes. The washed substrate is placed in a protective gas container that is not higher than 50 degree Celsius. An electrode substrate oxidized graphene quantum dot film is formed between the first and second electrodes for measuring humidity. USE - Method for preparing an oxidized graphite alkene quantum point humidity sensor. ADVANTAGE - The method enables preparing an oxidized graphite alkene quantum point humidity sensor with quick response speed, high wet erosion resistance and strong anti-electromagnetic interference ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an oxidation graphite alkene quantum point humidity sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an oxidized graphite alkene quantum point humidity sensor.
