Embodiment 1
[0054] Preparation method of ion sensor based on MXene electrode
[0055] (1) Preparation of ionic polymer layer solution: 0.5g ionic liquid EMIBF 4 and 1.0 g of thermoplastic polyurethane (TPU) were added into 15 g of DMF, and stirred at 70° C. for 10 hours at a speed of 600 r / min, and the obtained TPU ionic liquid solution was the ionic polymer layer solution.
[0056] (2) Preparation of ionic polymer membrane: the area is 25*75mm 2 Place the glass sheet template horizontally in the heating box, and adjust the temperature in the heating box to 70°C. Then use a pipette gun to take out 1ml of the ionic polymer layer solution each time and drop it onto the glass slide for a total of 2 drops. Dry it in a heating box for 2 hours, and then take it out to prepare an ionomer membrane.
[0057] (3) Place the ionomer film on the glass plate horizontally on the heating platform, and adjust the temperature to 45°C. Then drop-coat 2ml of 10mg / ml MXene electrode solution on the surfac...
