High-elasticity electroluminescent fiber and preparation method thereof

Abstract

The invention belongs to the technical field of intelligent electronic devices, and particularly relates to a high-elasticity electroluminescent fiber and a preparation method thereof. The method comprises preparing a frozen cross-linked hydrogel ion conductor as a transparent and high-elasticity electrode; and preparing a polydimethylsiloxane oligomer-electroluminescent powder mixed light-emitting active material with extrusion formability to be further cured and formed after extrusion. The multi-channel parallel extrusion needle head is designed, so that the light-emitting active layer is wrapped with two gel electrodes which are arranged in parallel, and the viscosity of the mixed light-emitting active material can ensure that the extruded fiber structure does not deform after the viscosity of the mixed light-emitting active material is controlled. The polydimethylsiloxane and the conductive gel have high elasticity, and the final luminescent fiber can still keep normal work when the tensile strength reaches up to 800%, the stable circulating tensile quantity can reach 300%, the cycling stability is more than 100 times, and the highest luminous brightness reaches 242. 6cd / m2. The light-emitting fibers can be further woven into clothes, and have very high wearing comfort and attractive light-emitting effects.

Description

technical field [0001] The invention belongs to the technical field of intelligent electronic devices, and in particular relates to a high-elastic electroluminescence fiber and a preparation method thereof. Background technique [0002] With the increasing demand for electronic products in people's life, the concept of "smart clothing" has gradually entered people's field of vision. By integrating electronic devices with sensing functions, light-emitting functions, energy storage functions, etc. Functions for monitoring human health, solar power generation, and as a power source to power electronic devices. Among them, the integration of light-emitting functions has great potential in night warning, signal transmission, fashion and beauty, and has a good commercial application prospect. The current luminescent materials can be divided into DC luminescent materials and AC luminescent materials. DC luminescent materials are divided into inorganic materials and organic materia...

AI Technical Summary

Problems solved by technology

The current luminescent materials can be divided into DC luminescent materials and AC luminescent materials. DC luminescent materials are divided into inorganic materials and organic materials. Integration, organic materials are small molecules or polymer active materials, such as 8-hydroxyquinoline aluminum, MEH-PPV, etc., which have good flexibility, but their preparation process often involves vacuum, the device cost is high, and the device is resistant to water and isolation Oxygen requirements are very high, it is difficult to resist the complex external environment faced by people's actual clothes, and the light-emitting devices are all planar structures, which cannot be integrated with fabrics in a large area
