Problems solved by technology

However, today’s high-barrier film products are generally rolled up directly after coating, without protection for the barrier layer, and the barrier layer is brittle during the winding process, especially the inorganic barrier layer coated by sputtering and atomic layer deposition technology; in addition , the outer surface of the high-barrier film product is easily damaged during the subsequent roll-to-roll composite processing, handling, and loading and unloading process with other films, which will cause the coating of the barrier layer to fall off and puncture, resulting in a significant decline in the overall water and oxygen barrier performance of the high-barrier film reduce

Embodiment 1

[0024] combine figure 1 As shown, the high barrier film of this embodiment includes: a substrate 1 , a barrier layer 2 and a hardened layer 3 from bottom to top.

[0025] Wherein, the substrate 1 in the present invention is a general-purpose transparent polymer substrate, and the material and thickness of the substrate are not particularly limited, and can be freely selected according to the purpose of use. Specifically, polyester film, nylon film, polypropylene film, transparent fluororesin, polyamide, fluorinated polyamide, polyimide, polyimide amide, polyether amide, epoxy resin, polycarbonate, Polyurethane resin, polyether ethyl ketone ester, alicyclic polysulfone, polyethersulfone, polyacrylate, polyethyl ether, fluorene ring-modified polycarbonate, alicyclic denatured polycarbonate, fluorene ring-modified polyester, cycloolefin copolymer things etc. Preferred are polyethylene terephthalate films (PET), nylon films (PA). In the present invention, the thickness of the s...

Embodiment 2

[0033] combine figure 1 As shown, the high barrier film of this embodiment comprises: a substrate 1 , a barrier layer 2 , a flexible organic layer 4 and a hardened layer 3 from bottom to top.

[0034] The substrate 1 , the barrier layer 2 and the hardened layer 3 in this embodiment are all the same as those in the first embodiment. The difference between this embodiment and the first embodiment is that a flexible organic layer 4 is provided between the barrier layer 2 and the hardened layer 3 .

[0035] Wherein, the flexible organic layer 4 is, relative to the hardening layer 3 , specifically a photocurable resin, such as urethane acrylate, polyester acrylate, epoxy acrylate, polyol acrylate, epoxy resin, and the like. Low-functionality monomers are preferred, and acrylate monomers with less than (or equal to) 2-functionality are preferred, such as 1,6-hexanediol diacrylate, neopentyl glycol diacrylate, etc., which can be used alone, Combinations are also possible. The phot...

Abstract

The invention discloses a high barrier film and a composite film, the high barrier film comprises a polymer substrate and a barrier layer, one side or both sides of the polymer substrate is / are provided with the barrier layer, at least one side outer surface of the high barrier film is provided with a hardened layer, and the hardened layer is light cured resin. The high barrier film capable of improving scratch resistance and puncture resistance is provided and aims at shortcomings of being easy to rupture and scratch in roll-to-roll processing and transportation and handling processes of high barrier films in the prior art, a stable high water and oxygen barrier property can be ensured.

Description

technical field [0001] The invention belongs to the field of flexible films, in particular to a high-barrier film and a composite film. Background technique [0002] Flexible thin-film solar cells such as OPV (Organic Photovoltaic) and CIGS (Copper Indium Gallium Selenium) are widely used in solar backpacks, solar tents, solar flashlights, solar cars, and even solar sailboats due to their unique flexibility and thinness. and on the plane. Another important application area is photovoltaic building integration, which can be tiled on the roof and pasted on windows, exterior walls and interior walls without support. [0003] Organic light-emitting diodes (OLEDs) have significant advantages in flat-panel displays, such as high luminance, rich colors, low-voltage DC drive, and simple manufacturing processes. In less than 20 years, OLEDs have entered the stage of industrialization. [0004] Flexible thin-film solar cells and OLEDs are easily affected by water and oxygen, resulti...
