COMPOSITE MATERIALS, COMPOSITE FILM MANUFACTURED BY USING THE SAME AND METHOD FOR MANUFACTURING COMPOSITE FILM}

The present invention relates to a composite material comprising a glass cloth and an organic-inorganic hybrid composition, a composite film made therefrom and a method for producing the composite film.

This application claims the benefit of the filing date of Korean Patent Application No. 10-2007-0105176 filed with the Korea Patent Office on October 18, 2007, the entire contents of which are incorporated herein.

Glass substrates used in display devices, frames, crafts, containers, etc. have many advantages such as small coefficient of linear expansion, excellent gas barrier property, high light transmittance, excellent surface flatness, excellent heat and chemical resistance, but they are fragile and easily broken. The high density has a heavy disadvantage.

Recently, as the interest in liquid crystals, organic light-emitting display devices, and electronic papers is rapidly increasing, studies are being actively conducted to replace these substrates from glass to plastic.

Substituting a glass substrate with a plastic substrate with a basic plastic film and a functional coating layer can lighten the overall weight of the display device, provide design flexibility, and is resistant to impact. When manufactured by a continuous process, It can be economical.

Here, in order to use the plastic film in the display device, the process temperature of the transistor element, the high glass transition temperature that can withstand the deposition temperature of the transparent electrode, the oxygen and water vapor barrier properties to prevent aging of the liquid crystal and the organic light emitting material, and the process temperature Small coefficient of linear expansion and dimensional stability to prevent warpage of substrates due to changes, high mechanical strength compatible with process equipment used in conventional glass substrates, chemical resistance to etch process, high light transmittance and low birefringence, Properties such as scratch resistance of the surface are required.

The low coefficient of linear expansion (CTE) is particularly important among the required physical properties of the plastic film for a display device, and a method of manufacturing a plastic film using glass cloth is one of the methods of providing a substrate having a low coefficient of linear expansion. .

To achieve low CTE values, tightly woven glass crosses should be used. In other words, the narrower the weaving interval of the glass cross, the lower the coefficient of linear expansion can be provided after the plastic film is manufactured.

However, glass crosses can be blended with organics such as epoxy or When the film is used together, there is a limit to using a densely woven glass cross due to air bubbles generated between glass fibers, and low interface adhesion between the glass cross and the organic material. Because of this, cracks may be generated at the interface.

US 2005/0203239 describes a method for curing a film by impregnating glass crosses with an organic material such as an epoxy or a polymer as an example of producing a film using an organic material and a glass cross together.

However, in this case, the adhesive strength at the interface between the glass cross and the organic material is insufficient, and in order to solve this problem, a method of modifying the surface of the glass cross is used, but there is still a problem in that an interface crack is generated due to low interface adhesion. have.

In addition, when manufacturing a film by impregnating glass cross with an organic material such as epoxy or polymer, there is a problem that productivity is low due to a long process time for curing or solvent volatilization.

In addition, when manufacturing a film by impregnating a glass cross with an organic material such as an epoxy or a polymer, it is difficult to remove air bubbles generated between the glass crosses due to high viscosity, and to improve the process, the process may be performed at a high temperature. Although it may proceed or in vacuum, there is a problem that the process is not easy because the process is complicated.

In addition, when the film is prepared by impregnating glass cross into an organic material such as an epoxy or a polymer, a lamination process is used, but there is a problem that it is difficult to perform a continuous process.

An object of the present invention is to provide an interfacial crack and bubble generation of glass fibers, and to provide a composite material having improved productivity, a composite film produced therefrom, and a method for producing the composite film.
