Referring to fig. 1, an embodiment of the present application provides a multifunctional device 10. The multifunction device 10 includes a substrate 100, a first composite layer 200, a second composite layer 300, and an electrolyte layer 400. The first composite layer 200 covers the surface of the substrate 100. The first composite layer 200 includes an actuation region 230 and a capacitance region 240. The first composite layer 200 and the substrate 100 have different thermal expansion coefficients. The second composite layer 300 is located in the capacitor region 240. The second composite layer 300 covers the surface of the first composite layer 200 away from the substrate 100. The electrolyte layer 400 is located in the capacitor region 240. The electrolyte layer 400 is sandwiched between the first composite layer 200 and the second composite layer 300. In the capacitor region 240, the first composite layer 200, the second composite layer 300, and the electrolyte layer 400 constitute a capacitor structure.
The substrate 100 may be used to support the first composite layer 200, the second composite layer 300, and the electrolyte layer 400. The substrate 100 may be a flexible material. The substrate 100 may be an organic material. The substrate 100 may have a rectangular shape. The actuation region 230 and the capacitance region 240 may be disposed at both sides of the substrate 100, respectively. The first composite layer 200 may be attached to the actuation zone 230 and the capacitance zone 240.
Referring to fig. 2, because the thermal expansion coefficients of the first composite layer 200 and the substrate 100 are different, the substrate 100 and the first composite layer 200 deform to different degrees when the first composite layer 200 or the substrate 100 is heated. The first composite layer 200 or the substrate 100 may be heated by light irradiation, or may be electrically powered to convert electric energy into thermal energy. The actuation zone 230 may bend. In the actuation zone 230, the substrate 100 and the first composite layer 200 constitute an actuation structure. The actuating structure can convert external energy into mechanical energy, and the actuating structure can be applied to the fields of biomedicine and wearable electronics.
In the capacitor region 240, the first composite layer 200, the electrolyte layer 400, and the second composite layer 300 are sequentially arranged to constitute the capacitor structure. The first composite layer 200 and the second composite layer 300 may have conductive and capacitive characteristics. The first composite layer 200 and the second composite layer 300 may constitute two plates of the capacitor structure. The electrolyte layer 400 may be polyvinyl alcohol-sulfuric acid (PVA-H) coated on the surfaces of the first and second composite layers 200 and 3002SO4) The solution is solidified. The capacitive structure may be a supercapacitor. The super capacitor can have the characteristic of rapid charge and discharge of the capacitor, and also can have the energy storage characteristic of a battery. The super capacitor also has flexibility, portability and high electrochemical performance, and can be widely applied to the field of wearable electronics. In the capacitance region 240, the first composite layer 200, the electrolyte layer 400, and the second composite layer 300 constitute the supercapacitor.
In the multifunction device 10 provided in the embodiment of the present application, the first composite layer 200 includes an actuation region 230 and a capacitance region 240. The thermal expansion coefficients of the first composite layer 200 and the substrate 100 are different, so that in the actuation zone 230, the first composite layer 200 and the substrate 100 deform to different degrees when heated to different degrees, and therefore actuation changes such as bending can be generated, so as to form an actuation structure. In the capacitance region 240, the first composite layer 200, the electrolyte layer 400, and the second composite layer 300 constitute an ultracapacitor. The super capacitor has a greater power density and a longer cycle life. The actuating structure and the super capacitor are integrated to form an integral structure, so that the occupied space of the multifunctional device 10 can be reduced, and the multifunctional device is convenient to carry. The actuation function or the capacitance function of the multifunction device 10 can also be used as desired, with ease of use.
In one embodiment, the first composite layer 200 includes a first graphite paper 210 and two first polyaniline layers 220. The second composite layer 300 may include a second graphite paper 310 and two second polyaniline layers 320. The two first polyaniline layers 220 are formed on two opposite surfaces of the first graphite paper 210, respectively. The two second polyaniline layers 320 are formed on two opposite surfaces of the second graphite paper 310, respectively. The two first polyaniline layers 220 can be obtained by chemically reacting on the surface of the first graphite paper 210. The two second polyaniline layers 320 can also be obtained by chemically reacting on the surface of the second graphite paper 310. The composition of the first graphite paper 210 and the composition of the second graphite paper 310 may be the same. The first polyaniline layer 220 and the second polyaniline layer 320 may have the same composition. The graphite component in the first graphite paper 210 may be used to absorb light to deform, or when the first composite layer 200 is energized, electrical energy is converted into thermal energy, and the first graphite paper 210 is easily heat conductive, so that the first composite layer 200 is easily deformed. In the actuation zone 230, the substrate 100 is deformed by the first composite layer 200, thereby generating an actuation effect.
The polyaniline has the material characteristics of pseudo capacitance. Therefore, in the capacitance region 240, the super capacitor formed by the first composite layer 200, the electrolyte layer 400 and the second composite layer 300 has a stronger energy storage capacity and a larger power density.
Referring to fig. 3, in one embodiment, the substrate 100 includes two supporting portions 110 and two connecting portions 120 spaced apart from each other. The connection part 120 may connect between the two support parts 110. That is, both ends of the connecting portion 120 are connected to the two supporting portions 110, respectively. I.e. the substrate 100 may constitute a U-shaped structure. The first composite layer 200 formed on the surface of the U-shaped structure may also be a U-shaped structure. The actuation structure may be located at an open portion of the U-shaped structure. The actuation structure is less resistant to bending.
Referring to fig. 4, in one embodiment, the second composite layer 300 includes two second sub-composite layers 330. The two second sub-composite layers 330 are respectively attached to the surfaces of the electrolyte layer 400 away from the two support portions 110. That is, the perpendicular projections of the two second sub-composite layers 330 on the substrate 100 fall on the surfaces of the two supporting portions 110, respectively. Thus, each of the second sub-composite layers 330 and the electrolyte layer 400 and the first composite layer 200 corresponding to the second sub-composite layers 330 constitute two of the supercapacitors.
In one embodiment, the two spaced apart supports 110 are arranged in parallel. Therefore, the two super capacitors are arranged in parallel on the same plane, and the carrying and the use are convenient.
Referring to fig. 5, two ends of any one of the supporting portions 110 may be powered on to form a single super capacitor.
Referring to fig. 6, two supercapacitors connected in series can be formed by connecting two supporting parts 110 with electricity respectively.
Referring to fig. 7, two ends of the two support parts 110 arranged in parallel in the same direction may be electrically connected to form two parallel supercapacitors.
Referring to fig. 8, in one embodiment, the supporting portions 110 of two multifunctional devices 10 may be electrically connected in sequence, and four supercapacitors connected in series may be formed.
The two super capacitors can be connected through a lead to form a series capacitor, a parallel capacitor and other structures.
In one embodiment, in the actuation zone 230, the surface of the substrate 100 facing away from the first composite layer 200 is provided with a plurality of grooves 130. The grooves 130 may reduce the resistance to deformation of the substrate 100, thereby increasing the flexibility of deformation of the actuation structure.
In one embodiment, the actuation zone 230 and the capacitance zone 240 are disposed adjacent to the first composite layer 200. The actuation zone 230 occupies an area no less than one-half of the surface area of the first composite layer 200. The actuation region 230 and the capacitance region 240 may be both rectangular, two rectangles are adjacently disposed, and the widths of the two rectangles may be the same. The length of the rectangle as the actuation region 230 may be not less than half of the length of the first composite layer 200, and thus the area occupied by the actuation region 230 may be not less than half of the surface area of the first composite layer 200. Thus, the actuation zone 230 may have a greater magnitude of deformation after being heated, reducing the resistance to deformation of the actuation zone 230.
The embodiment of the present application further provides a manufacturing method of the multifunctional device 10. The method comprises the following steps:

In S10, a large composite layer may be first manufactured, and then the first composite layer 200 and the second composite layer 300 may be formed by cutting.

Firstly, the area of 25cm can be taken2Graphite paper with thickness of 25 μm is soaked in 20ml of 0.02mol L-1Aniline in hydrochloric acid solution for one hour. The mass ratio of polyaniline compounded on the graphite paper can be accurately controlled through the difference of polymerization times.
In one embodiment, the carbon material in the graphite paper may be carbon nanotubes, graphene, two-dimensional metal carbide nanoplatelets, graphite, fullerenes, derivatives thereof, and the like.
In the S12, 20ml of ammonium persulfate aqueous solution is uniformly dripped on the soaked graphite paper and placed in the environment of 0 ℃ for complete reaction for 12 hours.

In one embodiment, before the step of S12, the method further comprises the step of pre-cooling the aqueous ammonium sulfate solution.
