Embodiment 1

[0047](1) Preparation of substrate film

[0048] Utilize the gravure coating method to form a 300nm polyamide layer on one side of a polyethylene terephthalate (PET, polyethyleneterephthalate) film with a thickness of 100um, and utilize the gravure coating method to coat the above polyethylene terephthalate The opposite side forms a 3um hard coating.

[0049] The polyamide layer-forming resin composition used at this time was prepared by mixing solid polyamide with ethanol.

[0050] (2) Preparation of transparent electrode film

[0051] A coating composition containing poly(3,4-ethylenedioxythiophene) as an active ingredient is coated on the upper surface (polyamide layer) of the substrate film prepared above, and dried to form a conductive film with a thickness of 200 nm. The polymer transparent electrode layer is used to prepare a transparent electrode film.

Embodiment 2

[0053] (1) Preparation of substrate film

[0054] A 300 nm polyamide layer was formed on one side of a polyethylene terephthalate film having a thickness of 100 um by gravure coating, and a 3 um hard coat layer was formed on the underside of the polyamide layer by gravure coating.

[0055] (2) Preparation of transparent electrode film

[0056] Coating a coating composition comprising poly(3,4-ethylenedioxythiophene) as an active ingredient on the base film prepared above, and drying to form a conductive polymer transparent electrode layer with a coating film thickness of 200 nm , to prepare a transparent electrode film.

Abstract

The invention relates to a base film for a transparent electrode film and the transparent electrode film using the same, and more particularly to the base film used for the transparent electrode film and the transparent electrode film using the same, wherein the base film has advantages of excellent dimension stability, effective transparency improvement and effective heat resistance improvement. The base film comprises the components of a base layer; and a dimension stabilizing layer which is formed on one surface or two surfaces of the base layer. The base film is used as a thermoplastic engineering plastic and has advantages of high impact resistance, high heat resistance, high moisture resistance and excellent tensible strength property.

Description

technical field [0001] The present invention relates to a base film for a transparent electrode film excellent in dimensional stability and a transparent electrode film using the base film, and more specifically relates to a base film having excellent dimensional stability, thereby improving transparency and heat resistance A substrate film for a transparent electrode film and a transparent electrode film utilizing the substrate film, the substrate film includes: a substrate layer; and a dimensionally stable layer formed on one or both sides of the substrate layer, as a thermoplastic engineering plastic, Excellent impact resistance, heat resistance, moisture resistance, and tensile strength properties. Background technique [0002] The touch panel is set on a cathode ray tube (CRT, CathodeRayTube), a liquid crystal display device (LCD, LiquidCrystalDisplay), a field emission display device (FED, FieldEmissionDisplay), a plasma display panel (PDP, PlasmaDisplayPanel) and an e...
