Dielectric adhesive film for electronic paper display device

Номер: US20130171399A1

Принадлежит: Toray Advanced Materials Korea Inc

A dielectric adhesive film for an electronic paper display device. A lower electrode to which voltage is applied and an image upper electrode coated with charged particles whose colors are changed depending on the applied voltage are attached to the adhesive film. Thickness of the adhesive film is controlled to be uniform and constant, and a resistance value in the thickness direction of the adhesive film, i.e., a resistance value in the direction where an electric field is formed, is controlled without changing adhesive properties and reliability as the thickness of the adhesive film is controlled. Since loss of the applied voltage is minimized and the charged particles are freely driven, driving performance of the display device is excellent although a high voltage is not applied in driving a flexible display device, such as a flexible LED, an organic electro luminescence (EL) element including an electronic paper, and the like.

Принадлежит: University of Utah Research Foundation UURF

Described herein is the synthesis of adhesive complex coacervates and their use thereof. The adhesive complex coacervates are composed of a mixture of one or more polycations and one or more polyanions. The polycations and polyanions in the adhesive complex coacervate are crosslinked with one another by covalent bonds upon curing. The adhesive complex coacervates have several desirable features when compared to conventional bioadhesives, which are effective in water-based applications. The adhesive complex coacervates described herein exhibit good interfacial tension in water when applied to a substrate (i.e., they spread over the interface rather than being beaded up). Additionally, the ability of the complex coacervate to crosslink intermolecularly increases the cohesive strength of the adhesive complex coacervate. They have numerous biological applications as bioadhesives and drug delivery devices and are particularly useful in underwater applications and situations where water is present such as, for example, physiological conditions.

[Summary] The present invention relates to a touch panel. The present touch panel has a shape that comprises a plastic substrate film and a pressure sensitive adhesive layer attached to said substrate film. Here, a phenomenon of penetrating oxygen, moisture or other foreign materials into an interface between said substrate film and said pressure sensitive adhesive layer is prevented, and decrease of optical properties by bubble generation due to the out-gassing phenomenon in the plastic substrate film is prevented. In addition, even if the pressure sensitive adhesive layer is directly attached to the conductive thin film, and it is exposed to a severe condition such as high temperature or high temperature and high humidity condition as such a state, change of resistance in the conductive thin film is effectively inhibited. Therefore, the present touch panel may be stably driven for a long time.
