Description
Technical Field
The invention belongs to the technical field of intelligent driving and sensing, and relates to an MXene-GO/adhesive tape composite Janus structure, and preparation and application thereof.
Background
With the advancement of personalized healthcare systems, researchers are focusing on developing the most advanced flexible wearable electronics to monitor human body motion. Therefore, stretchable and flexible electronic devices have received much attention and are widely used in the fields of sensors, drivers, electronic displays, human-computer interaction, soft robots, artificial organs, and personalized medical devices. Therefore, the multifunctional intelligent material integrating the sensor and the driver has high research value.
Most of the currently researched drivers or sensors face the disadvantages of complex preparation method, single driving or sensing source, poor repeatability and the like. More importantly, some drivers do not have sensing capability, sensors do not have driving function, and the drivers and the sensors cannot be used together.
MXene is a novel two-dimensional metal-based carbide, has excellent hydrophilicity, conductivity and photothermal conversion performance, can respond to external stimuli such as relative humidity, light, electricity and the like, and is one of the best candidate materials for preparing actuators. However, simple MXene is unstable under environmental conditions and is easily oxidized and deteriorated, resulting in loss of excellent performance. Accordingly, the present invention has been made in view of the above problems.

The invention aims to provide an MXene-GO/adhesive tape composite Janus structure, and preparation and application thereof.
The purpose of the invention can be realized by the following technical scheme:
one of the technical schemes of the invention provides an MXene-GO/adhesive tape composite Janus structure, which comprises an adhesive tape structure and an MXene-GO structure compounded on the adhesive tape structure, wherein the MXene-GO structure is formed by compounding MXene and GO. MXene and GO are uniformly mixed in a solution mode and are in a layer-by-layer stacked arrangement state.
Further, the adhesive tape structure is an adhesive tape with hydrophobic property, which includes but is not limited to BOPP adhesive tape.
Further, the MXene-GO structure is an MXene-GO composite membrane, wherein the MXene mass fraction is 50% -80%.
Further, the thickness of the adhesive tape structure is 7-15 μm, and the thickness of the MXene-GO structure is 9-20 μm.
Further, MXene is Ti3C2Tx MXene。
The second technical scheme of the invention provides a preparation method of an MXene-GO/adhesive tape composite Janus structure, which comprises the following steps:
(1) adding the MXene solution into the GO solution, and uniformly mixing by ultrasonic to obtain an MXene-GO solution;
(2) carrying out vacuum filtration on the obtained MXene-GO solution to form a film, and drying to obtain an MXene-GO composite film attached to the substrate;
(3) peeling the MXene-GO composite membrane from the substrate, and combining one side of the MXene-GO composite membrane with the adhesive tape structure to obtain the target product.
Furthermore, in the step (1), the concentration of the MXene solution is 1-3 mg/mL, preferably 2mg/mL, and the concentration of the GO solution is 1-3 mg/mL, preferably 2 mg/mL.
Further, in the step (1), the addition amounts of the MXene solution and the GO solution meet the following requirements: MXene accounts for 60-80% of the total mass of solutes in the MXene-GO solution, and is optionally 75%.
The third technical scheme of the invention provides application of an MXene-GO/adhesive tape composite Janus structure, and the composite Janus structure is used as a driver or a sensor and is used in the fields of intelligent driving, bionics or sensing.
Further, when the composite Janus structure is used as a driver, the composite Janus structure is bent and deformed based on humidity, infrared illumination or voltage change of the corresponding external part, so that driving is realized.
When the composite Janus structure is used as a sensor, a copper wire is led out to serve as an output end, and the change of the resistance value is generated based on the change of the humidity, the infrared illumination or the voltage of the corresponding external part, so that the sensing response is realized. More specifically, when the MXene-GO composite Janus structure is used for monitoring human body movement in the field of medical health, the MXene-GO composite Janus structure specifically comprises the following steps: different resistance signal responses are generated according to different bending change amplitudes of different joint parts of human body movement to distinguish movement modes, the larger the movement amplitude is, the larger the curvature of the MXene-GO composite Janus structure is, and the larger the resistance change rate of the MXene-GO composite Janus structure is; and monitoring the movement frequency according to the membrane resistance change signal generated by the amplitude change of the continuous movement of the human body.
When the MXene-GO composite Janus structure is used for pressure sensing monitoring in the sensing field, the pressure sensing monitoring method specifically comprises the following steps: the magnitude of pressure is distinguished by generating different resistance signal responses according to different pressures applied to the MXene-GO composite Janus structure, and the larger the applied pressure is, the larger the resistance change rate of the MXene-GO composite Janus structure is; and transmitting an output signal according to a change in membrane resistance caused by the change in pressure.
When the MXene-GO composite Janus structure is used for driving and interacting with the sensing field, the MXene-GO composite Janus structure specifically comprises the following steps: according to an external stimulus applied to the MXene-GO composite Janus structure, the MXene-GO composite Janus structure is subjected to bending deformation, and different resistance signal responses are generated. The deformation state of the MXene-GO composite Janus structure can be judged by analyzing the output resistance signal.
MXene is a two-dimensional metal-based carbide material. Has excellent physical and chemical properties. However, simple MXene films are not stable in the environment. GO is one of important derivatives of graphene-based materials, and is introduced into MXene, so that the GO can be coated on the surface of the MXene to inhibit the MXene from being oxidized, and the stability and response sensitivity of an actuator are improved. Meanwhile, in order to prepare a stretchable and flexible electronic device, a commercially available BOPP adhesive tape is selected. By forming a Janus structure, the mechanical property of the MXene-GO/adhesive tape composite material is remarkably improved, and the BOPP serves as a stimulus response inert layer to enable the driver to respond to humidity stimulus, infrared light stimulus and voltage stimulus. Furthermore, due to the hydrophobic nature of the BOPP tape, the Janus structure of MXene-GO/tape further exhibits self-cleaning properties when contaminated.
The MXene-GO structure is used as an active layer for sensing and driving, the corresponding resistance value can change along with the changes of relative humidity, infrared illumination, applied voltage, stretching and pressure conditions, and when the applied conditions change, the distance between layers of the MXene-GO structure can change from one layer to another.
The driver and the sensor of the MXene-GO/adhesive tape composite Janus structure further comprise a lead-out copper wire, so that the flexible sensor is obtained.
In the preparation process of the MXene-GO/adhesive tape composite Janus structure, an MXene-GO film obtained after vacuum filtration and drying is directly pasted and cut with an adhesive tape to obtain the MXene-GO/adhesive tape composite Janus structure driver, the complex and toxic process is effectively avoided, the mechanical performance is good, and the high-sensitivity flexible sensor is obtained by leading out a copper wire.

(6) and (4) taking the lead copper wire as an output end to obtain the GO/adhesive tape composite Janus structure sensor.
Example 2
A method for preparing drivers and sensors with MXene/adhesive tape composite Janus structures comprises the following specific steps:
(1) MXene solution is prepared by adopting a liquid etching method, and the preparation method is shown in the above document;
(2) preparing MXene solution into 2mg/ml, introducing inert gas, and uniformly dispersing by ultrasonic;
(3) carrying out vacuum filtration on the uniformly dispersed MXene solution to form a film;
(4) and (3) peeling off the film from the substrate after freeze drying to obtain the MXene film.

(6) and (5) taking the lead copper wire as an output end to obtain the MXene/adhesive tape composite Janus structure sensor.
Example 3
A method for preparing drivers and sensors of MXene-GO/adhesive tape composite Janus structures comprises the following specific steps:
(1) MXene solution is prepared by adopting a liquid etching method, and the preparation method is shown in the literature[1](ii) a Will preparePreparing MXene solution to 2mg/ml, and uniformly mixing by ultrasonic treatment for 10 min;
(2) preparing GO into a solution of 2mg/ml, and introducing inert gas to the solution to perform uniform ultrasonic dispersion;
(3) mixing MXene solution and GO solution according to the volume ratio of 3:1, introducing inert gas, and performing ultrasonic dispersion uniformly;
(4) carrying out vacuum filtration on the uniformly mixed MXene-GO solution to form a film;
(5) and (3) peeling off the film from the substrate after freeze drying to obtain the MXene-GO composite film.
(6) After the dried MXene-GO composite membrane is stripped from the substrate, one side of the dried MXene-GO composite membrane is combined with an adhesive tape to obtain an MXene-GO/adhesive tape composite Janus structure driver;
(7) and (4) taking the lead copper wire as an output end to obtain the MXene-GO/adhesive tape composite Janus structure sensor.
With reference to fig. 1 to 7, a drive test was performed on the GO/tape composite Janus structure film material driver manufactured in this example 1, and GO has no conductivity, so that GO cannot be electrically driven and has no sensing performance.
When the MXene/tape composite Janus-structured film material driver prepared in this embodiment 2 is subjected to sensing test, the MXene itself has good conductivity, so that the bending deformation motion of the film does not cause the output electrical signal to change significantly, and the sensing performance is poor.
The MXene-GO/adhesive tape composite Janus structure film material driver prepared in this embodiment 3 was subjected to a structural test, and it was observed that the cross section thereof exhibited a layer-by-layer stacking arrangement state, which was beneficial to adsorption and desorption of water molecules. The bending test shows that the MXene-GO/adhesive tape material can reach a bending angle of 150 degrees under wet driving, and the change value of a sensing resistance signal is increased along with the increase of humidity and can reach about 50 percent at most. The change value of the sensing resistance signal is reduced along with the increase of the optical density value at a bending angle of 160 degrees under the driving of light, and the maximum change value can be reduced by about 60 percent. Meanwhile, due to the excellent electric heating performance of MXene, the driver has good low-voltage driving performance, a bending angle of 360 degrees can be achieved under the driving voltage of 4.5V, the deformation can be realized, meanwhile, the change value of an electric signal can also be changed, the change value of a sensing resistance signal is reduced along with the increase of the applied voltage value, and the maximum reduction can be about 23%. .
In summary, the MXene-GO composite membrane is used as an active material of a driver and a sensor, a commercial BOPP adhesive tape is selected as an inert material of the driver and the sensor, the driver and the sensor with Janus structures are constructed, a copper wire is led out to serve as a device electrode, electrochemical signal monitoring is carried out to respond to a series of external condition changes, as shown in figure 5, the resistance change rate of the sensor is increased along with the increase of strain, three sections of linear responses are divided in a strain range from-35% to 60%, and GF represents response sensitivity. We apply this to the finger bend test, and it can be seen in fig. 6 that as the finger bend angle increases, the rate of change of resistance also increases. Pressure sensing tests were also performed on the MXene-GO/tape material, and as a result, as shown in FIG. 7, it can be seen that the resistance change rate of the MXene-GO/tape material gradually increases with the increase of the pressure, and the MXene-GO/tape material has a larger response value than the MXene/tape material.
The MXene in the invention can be a single-layer MXene obtained by selectively etching the A layer in the precursor MAX with HCl and LiF, and then carrying out ethanol intercalation, ultrasonic dispersion and centrifugal washing. And ultrasonically mixing the graphene oxide and GO solution, and performing vacuum filtration and drying to obtain the composite membrane. And further pasting a layer of BOPP adhesive tape to obtain the driver with the MXene-GO/adhesive tape composite Janus structure, and further obtaining the high-sensitivity flexible sensor by means of leading out a copper wire. When external environmental conditions change, the MXene-GO/adhesive tape composite Janus structure receives stimulation to generate bending deformation, and meanwhile, the distances among the sheets and the layers in the MXene-GO structure can be changed, so that the number of conductive paths is increased or reduced, and the resistance is changed. The pure GO/adhesive tape composite Janus structure without MXene is not conductive, and when the external environmental conditions change, the distances between sheets and layers in the GO structure can be changed, but no resistance change signal is generated. And the pure MXene/adhesive tape composite Janus structure without GO is not added, and when the external environmental conditions change, the distances between the sheets and the layers in the MXene structure can be changed, but the resistance change range is not large.
When the MXene-GO composite membrane is applied to a driver, a sensor and the like, the MXene-GO composite membrane only has simple response to a humidity gradient; after the BOPP layer is added, the BOPP serves as a hydrophobic inert layer and can respond to humidity, illumination and voltage stimulation. The MXene-GO composite membrane only has resistance sensing to humidity; after the BOPP layer is added, the BOPP serves as a hydrophobic inert layer and can have sensing response to changes of humidity, illumination and voltage spike. The MXene-GO composite membrane only has resistance sensing to humidity, and after the BOPP layer is added, the BOPP serves as a hydrophobic inert layer and can have sensing response in the aspect of mechanics. Meanwhile, after the MXene-GO composite membrane is added with the BOPP layer, the BOPP layer is used as a hydrophobic inert layer, and the material has hydrophobic self-cleaning performance.
The embodiments described above are described to facilitate an understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention based on the disclosure of the present invention.
