embodiment 1
[0049]FIG. 1 is a schematic diagram of an exemplary structure of a composite film provided by Embodiment 1 of the present invention. As shown in FIG. 1, there may be a plurality of matrix membranes, that is, the composite film may include a plurality of matrix membranes which are stacked up. Preferably, the number of the matrix membranes is two to four. In this embodiment, the description is given by taking a case that the number of the matrix membranes is three as an example. The three matrix membranes are a matrix membrane 11, a matrix membrane 12 and a matrix membrane 13, respectively. The matrix membrane 11, the matrix membrane 12 and the matrix membrane 13 are stacked up, here, the matrix membrane 11 is located on the matrix membrane 12, and the matrix membrane 12 is located on the matrix membrane 13.
[0050]Preferably, the thickness of each of the matrix membranes is 1 μm-1000 μm. In this embodiment, as the thickness of each of the matrix membranes is 1μm-1000 μm, both the probl...
embodiment 2
[0055]FIG. 3 is a schematic diagram of an exemplary structure of a composite film provided by Embodiment 2 of the present invention. As shown in FIG. 3, the composite film includes one matrix membrane 31, and the matrix membrane 31 includes at least one waterproof film 311-319.
[0056]In this embodiment, there is one matrix membrane 31. Preferably, the thickness of the matrix membrane is 1 μm-1000 μm. In this embodiment, as the thickness of the matrix membrane is 1 μm-1000 μm, both the problem of poor mechanical performance and poor watertightness due to too small thickness of the matrix membrane and the problem of poor bendability and poor light transmission due to too large thickness of the matrix membrane may be effectively avoided, thus, not only good mechanical performance and watertightness of the matrix membrane but also good bendability and light transmission of the matrix membrane are ensured.
[0057]Preferably, the matrix membrane is a flexible film. The material of the matrix...
embodiment 4
[0067]FIG. 5 is a flowchart of a manufacturing method of a composite film of the present invention. As shown in FIG. 5, the method includes steps as follows.
[0068]At step 101, a matrix membrane precursor layer is formed.
[0069]FIG. 6a is a schematic diagram of forming a matrix membrane precursor layer in the manufacturing method of a composite film according to Embodiment 4 of the present invention. As shown in FIG. 6a, a matrix membrane precursor layer 61 is formed by spin-coating, blade-coating or spray-coating. The matrix membrane precursor layer 61 may be formed from flexible material.
[0070]At Step 102, at least one waterproof film is formed on the matrix membrane precursor layer.
[0071]FIG. 6b is a schematic diagram of forming waterproof films in the manufacturing method of a composite film according to Embodiment 4 of the present invention. As shown in FIG. 6b, waterproof films 62 are formed on the matrix membrane precursor layer 61 by placing, physical deposition or chemical d...
