preparation example Construction

[0045] According to another aspect of the present invention, there is also provided a method for preparing a polymer transparent conductive film, which includes the following steps: forming a conductive layer 200 on the resin base layer 100, and the conductive layer 200 has a plurality of resin base layers 100 the exposed gap 201 ; and forming a resin fixing layer 300 on the conductive layer 200 and the gap 201 .

[0046] In the polymer transparent conductive film formed by this method, a thin resin fixing layer 300 is provided on the conductive layer 200 . The resin fixed layer 300 has high flexibility, which can effectively improve the flexibility of the entire polymer transparent conductive film. At the same time, since the thickness of the resin fixed layer 300 is sufficiently thin, the conductive filler located in the conductive layer 200 can be exposed from the resin fixed layer 300 , so that the polymer transparent conductive film maintains high conductivity.

Abstract

The invention provides a high polymer transparent conductive film and a preparation method thereof. The high polymer transparent conductive film comprises a resin substrate layer, a conductive layer and a resin fixing layer, wherein the conductive layer is positioned above the resin substrate layer, and has a plurality of seams for allowing the resin substrate layer to expose; the resin fixing layer is positioned above the conductive layer and in the seams; the conductive layer comprises a conductive polymer and a conductive filler; the thickness of the resin fixing layer is smaller than 300 nm. According to the high polymer transparent conductive film, the resin fixing layer which is very thin is arranged above the conductive layer. The resin fixing layer is relatively high in softness, and can be used for effectively improving the softness of the whole high polymer transparent conductive film. More importantly, the seams for allowing the resin substrate layer to expose are formed in the conductive layer, so that the resin fixing layer above can penetrate into the seams and can be bonded with the resin substrate layer, and the adherence strength between the conductive film and the resin substrate layer can be effectively improved.

Description

technical field [0001] The invention relates to the field of transparent conductive film manufacturing, in particular to a polymer transparent conductive film and a preparation method thereof. Background technique [0002] At present, touch screen technology has been widely used in fields such as mobile phones, notebook computers, and tablet computers. Among them, transmissive capacitance, OGS (One Glass Solution, single-chip touch panel), in-cell, and on-cell are currently mainstream technologies. In addition, with the increasing size and thinning of touch screens, the OGS technology has more compressed the market share of the transmissive capacitive technology. The most critical core technology in touch screen technology is the use of ITO-Film (polymer transparent conductive film) in its entire assembly. ITO-film products are not only used on touch screens, but are also widely used in other flexible display devices, such as electronic paper books and OLEDs. On the other...
