Embodiment 1

[0032] Fabrication method of flexible thin film thermosensitive electrode with negative temperature coefficient, such as figure 1 shown, including the following steps:

[0033] S1. Configure MXene powder and PEDOT:PSS solution to mix to obtain a mixed solution. After the mixed solution is ultrasonically treated for 30 minutes, it is filtered by a vacuum filter to obtain a viscous mixed solution;

[0034] S2. Utilize a laser cutting machine to carry out laser cutting on the PET plate with double-sided adhesive to obtain a mold, and stick the side of the mold with double-sided adhesive to the carrier film;

[0035] S3. drop the PMMA solution into the mould, and obtain a solidified PMMA substrate by heating and drying in a blower oven;

[0036] S4. The PMMA substrate is placed in a plasma cleaning machine for surface modification, and the viscous mixed solution is evenly drip-coated on the PMMA substrate;

[0037] S5. Place the PMMA substrate after dripping the viscous mixed so...

Embodiment 2

[0039] S1. Configure the mixed solution obtained by mixing the MXene powder with a mass ratio of 3:1 and the PEDOT:PSS solution. After the mixed solution is ultrasonically treated for 30 minutes, filter paper with a pore size of 0.45 μm is used for suction filtration through a vacuum filter. Obtain a viscous mixture; in this step, ultrasonic treatment for 30 minutes can fully mix the MXene powder and PEDOT:PSS solution; the use of filter paper with a pore size of 0.45 μm can ensure the suction filtration effect and have a suitable suction filtration speed. (PEDOT:PSS is easy to pass through the filter paper when the pore size of the filter paper is too large, and the filtration speed is too slow if the pore size of the filter paper is too small);

[0040] S2. Utilize a laser cutting machine to carry out laser cutting on a PET plate with double-sided adhesive tape to obtain a mold, and stick the side of the mold with double-sided adhesive tape on the carrier film; wherein the th...

Abstract

The invention discloses a flexible thin film thermosensitive electrode with a negative temperature coefficient and a manufacturing method thereof. The manufacturing method includes: preparing and mixing MXene powder and a PEDOT:PSS solution to obtain a mixed solution, the mixed solution being subjected to ultrasonic treatment for 30 min and then subjected to suction filtration through a vacuum suction filter, and obtaining a viscous mixed solution; carrying out laser cutting on the PET plate pasted with the double-sided adhesive tape by using a laser cutting machine to obtain a mold, and pasting one surface, with the double-sided adhesive tape, of the mold on a glass slide; dropwise adding the PMMA solution into a mold, and heating and drying the PMMA solution in a blast drying oven to obtain a cured PMMA substrate; putting the PMMA substrate into a plasma cleaning machine for surface modification treatment, and uniformly dispensing the viscous mixed solution onto the PMMA substrate; and putting the PMMA substrate coated with the viscous mixed solution into a vacuum drying box, drying to form a film, and taking down the mold to obtain the flexible film thermosensitive electrode.

Description

technical field [0001] The invention relates to the technical field of thermosensitive electrodes, in particular to a flexible film thermosensitive electrode with a negative temperature coefficient and a manufacturing method thereof. Background technique [0002] As one of the sensitive elements, thermal electrodes can be divided into positive temperature coefficient thermal electrodes and negative temperature coefficient thermal electrodes according to their different response characteristics to temperature. Compared with ordinary electrodes, this type of electrode is highly sensitive to temperature, and can exhibit different resistance values ​​when the temperature is different. The resistance of the positive temperature coefficient thermistor electrode increases continuously with the increase of temperature, while the resistance of the negative temperature coefficient thermistor electrode is the opposite, and the resistance decreases continuously with the increase of temp...
