Abstract

The invention belongs to the technical field of intelligent electronic devices, in particular to a transparent conductive fiber, a preparation method thereof, and an application in a fabric display. The method of the invention comprises: compounding a polymer with an ionic liquid conductive component to prepare a transparent conductive raw material with uniform, stable and spinnable properties, and spinning it into a fiber through a spinning process. Transparent conductors are an indispensable part of light-emitting devices, and transparent conductive fibers play a key role in wearable display devices. Light-emitting pixel dots are formed at the place to form a fabric display, which has the same breathability and flexibility as everyday fabrics.

Description

technical field [0001] The invention belongs to the technical field of intelligent electronic devices, and particularly relates to a transparent conductive fiber, a preparation method thereof, and an application in a fabric display. Background technique [0002] Electronic fabrics provide infinite possibilities for the electronic digitalization of our daily life. The construction of electronic fabrics is realized by weaving a series of functional fibers. Among them, conductive fiber electrodes are the cornerstone of textile electronic systems. Researchers have developed a series of fiber electrodes based on metal materials, conductive polymer materials, and carbon nanomaterials.

However, for the construction of textile light-emitting display devices, as an indispensable part of the interaction between the textile electronic system and the outside world, we need a fiber electrode that takes into account multiple indicators such as transparency, conductivity, high flexibility, and tolerance. Develop suitable candidates

At present, the most widely used transparent electrode material for planar light-emitting devices is indium tin oxide (ITO), but its conductive film layer is brittle, and cracks are prone to failure when it is bent. In addition, transparent electrodes based on silver nanowires have high Flexible, but the nano-silver structure is easy to oxidize, the stability is not good, and the bonding force between the silver nanowire film layer and the substrate is limited. After the fiber electrode is made, the film layer is prone to damage during the weaving process and during use.
