Example Embodiment
[0026] Example 1:
[0027] a) 5g porous CuO and 5g graphene oxide were prepared into a uniformly dispersed suspension, and a CuO / rGO composite film was prepared by suction filtration with a thickness of 10 μm-30 μm.
[0028] b) Place the CuO / rGO composite film in 1g / L NIPAm monomer aqueous solution, and carry out plug-in reaction by selecting an ultrasonic horn with an ultrasonic frequency of 20kHz, and the ultrasonic power is 200W. The CuO / rGO@PNIPAm composite film was prepared as a temperature-responsive flexible electrode by ultrasonic-intermittent (N2 gas) circulation mode for polymerization reaction and cumulative ultrasonic irradiation for 1 h.
[0029] c) The CuO / rGO@PNIPAm composite film is used as the working electrode, the saturated calomel electrode (SCE) is used as the reference electrode, and the platinum electrode (Pt) is used as the auxiliary electrode. Put the three-electrode system into a weighing bottle filled with 5mM / L glucose NaOH solution, and t
