Description

Technical Field

[0001] The utility model relates to the technical field of dimming glass, in particular to a dimming glass and a vehicle. Background Art

[0002] In related technologies, EC dimming glass (Electrochromic Glass), that is, electrochromic glass, is to make laminated glass by compounding an EC dimming film with an adhesive film, or to first sputter an EC film layer on glass and then make laminated or insulating glass. At present, there are two production methods for EC dimming films, namely the organic material coating process and the inorganic material magnetron sputtering process. The dimming film products of both processes have problems of poor color change uniformity and short response time.

[0003] Specifically, for the EC dimming film layers produced by the coating process and the magnetron sputtering process, their key structures are all a conductive layer, an electrochromic layer, an electrolyte layer, and an ion storage layer. The difference is that the coating process can coat organic materials on a flexible film, while the magnetron sputtering process directly sputters inorganic materials onto the glass surface. The transparent conductive layers of both processes are metal films, and the common one is ITO (Indium Tin Oxide), that is, tin-doped indium oxide, whose sheet resistance is generally (10-60) Ω / square, and the ITO conductive film will be oxidized after being placed for a long time, resulting in a decline or failure of the ITO film performance. Among them, the problems of the organic EC dimming layer are that the color is blue, not the grayish black that users like. Because its EC layer is an organic material, its aging resistance is poor, and at the same time its response color change time is relatively long; the problems of the inorganic EC dimming glass are slow response time and inability to make large-curvature samples.

[0027] Next, refer to Figure 1 Describe the dimming glass 100 according to an embodiment of the present invention.

[0028] As Figure 1As shown, the dimming glass 100 according to an embodiment of the present utility model includes: a first glass layer 1, a second glass layer 2, a first conductive layer 3, a second conductive layer 4, an electrochromic layer 5, an electrolyte layer 6, and an ion storage layer 7.

[0029] Specifically, the first glass layer 1 and the second glass layer 2 are stacked. The first glass layer 1 and the second glass layer 2 are the most basic glass elements of the dimming glass 100 and the carriers for carrying other components. The first conductive layer 3 and the second conductive layer 4 are stacked between the first glass layer 1 and the second glass layer 2, that is, the first conductive layer 3 and the second conductive layer 4 are disposed between the first glass layer 1 and the second glass layer 2 and are stacked with the first glass layer 1 and the second glass layer 2. Among them, the first conductive layer 3 can be close to the first glass layer 1, and the second conductive layer 4 can be close to the second glass layer 2.

[0030] The electrochromic layer 5 is stacked between the first conductive layer 3 and the second conductive layer 4, that is, the electrochromic layer 5 is disposed between the first conductive layer 3 and the second conductive layer 4 and is stacked with the first conductive layer 3 and the second conductive layer 4. The electrolyte layer 6 is stacked between the electrochromic layer 5 and the second conductive layer 4, that is, the electrolyte layer 6 is disposed between the electrochromic layer 5 and the second conductive layer 4 and is stacked with the electrochromic layer 5 and the second conductive layer 4. The ion storage layer 7 is stacked between the electrolyte layer 6 and the second conductive layer 4, that is, the ion storage layer 7 is disposed between the electrolyte layer 6 and the second conductive layer 4 and is stacked with the electrolyte layer 6 and the second conductive layer 4.

[0031] The principle of the dimming glass 100 lies in the electrochromic technology, which allows the glass to change from a transparent state to a colored state, or from a colored state to a transparent state, providing flexibility in light control. This technology utilizes the electrochromic layer 5, and the electrochromic layer 5 can change color and adjust light in the energized state.

[0032] The electrochromic layer 5 is the core part of the dimming glass 100 and is composed of a mixed conductor material of electrons and ions. Under the action of an external electric field, the injection or extraction of ions in this layer causes a reversible change in colorless and colored states of the whole composition, thereby realizing the adjustment of the glass color. The first conductive layer 3 and the second conductive layer 4 serve as transparent electrodes for transmitting current, thereby controlling the color change of the electrochromic layer 5. The electrolyte layer 6 is also called an ion conductor layer and only allows ions to pass through, and is used to conduct ions during the color change process. The ion conductor layer ensures the effective transmission of ions during the electrochromic process, thereby ensuring a stable color change. The ion storage layer 7 is used to store ions to ensure that ions can be released from the storage layer under the action of an electric field and participate in the electrochromic process, thereby realizing the color change of the dimming glass 100.

[0033] Through the synergistic effect of the first conductive layer 3, the second conductive layer 4, the electrochromic layer 5, the electrolyte layer 6 and the ion storage layer 7, the dimming glass 100 can change color under the energized state, adjust the light transmittance, provide the characteristics of aesthetics, privacy and low energy consumption, and thus has unique advantages in fields such as automobiles.

[0034] In the related art, indium tin oxide (ITO) is usually used for the conductive layer, and its sheet resistance is generally (10 - 60) Ω / / . Moreover, when the ITO conductive film is placed for a long time, oxidation will occur, resulting in a decline or failure of the ITO film performance.

[0035] Graphene is a single-layer material composed of carbon atoms with a hexagonal grid structure. It has many excellent properties, such as good electrical conductivity, and its carrier mobility is 15000 cm 2 / V. In addition, graphene is flexible and transparent, and the visible light transmittance of a single layer is 97.7%. Its excellent electrical conductivity characteristics have been applied in many fields. In this application, the first conductive layer 3 and the second conductive layer 4 are graphene layers, that is, both the first conductive layer 3 and the second conductive layer 4 adopt graphene materials. Graphene has a small resistance and a large carrier concentration, and can conduct the circuit quickly as a whole, thereby shortening the color change response time and improving the color change uniformity of the product.

[0036] In this application, using graphene as the first conductive layer 3 and the second conductive layer 4 is simpler in manufacturing process, lower in cost and faster in response time than the inorganic EC dimming glass manufacturing process. Specifically, the dimming response time is shortened from the original minute level to less than 1 minute. The dimming time is shorter, and the user perception is more obvious, improving the comfort of the vehicle cockpit; the dimming glass 100 changes color uniformly as a whole, with basically no color difference, and has excellent aging resistance.

When the thicknesses of the first conductive layer 3 and the second conductive layer 4 are within the range of 0.2 nm - 100 nm, the current can be better transmitted, thereby controlling the color change of the electrochromic layer 5, ensuring the uniformity of the color change of the dimming glass 100 and shortening the response time of the color change of the dimming glass 100.
