▎ 摘　　要

NOVELTY - The method involves preparing MXene solution. The MXene solution is sealed and refrigerated for further use. An optical fibre is wound on an optical fibre fixing disc. The optical fibre is made into single-layer optical fibre sensitive disc. A preset amount of MXene solution is taken. An oxidized graphene, cellulose and heptahydrate zinc sulphate solution for ultrasonic and stirring are added to prepare mixed solution. The mixed solution is introduced into a self-made template. A single-layer optical fibre sensitive disc is put. A prefabricated copper sheet is placed below the self-made template. A freeze dried optical fibre sensitive disc is obtained based on MXene after finishing and placing a freeze-drying operation. USE - Method for preparing a sensing probe (claimed) based on an MXene. ADVANTAGE - The method enables preparing a MXene-based sensing probe, which has improved sensing sensitivity. DETAILED DESCRIPTION - The optical fibre sensitive disc is solidified based on MXene to obtain a cured optical fibre sensitive disc. Two ends of a surface of the optical fibre sensitive disc after curing are respectively connected with first Faraday rotating mirror and second bare optical fibre coupler. Other end of the bare optical fibre coupler is connected with second Faraday rotating mirror to obtain a sensing probe based on an MXene. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating amethod for preparing a MXene-based sensing probe. (Drawing includes non-English language text).
