preparation example Construction

[0071] By adopting the preparation method provided by the invention, composite spinning of the polymer and aggregation-induced luminescent AIE molecules is realized, so as to prepare composite luminescent fibers. Since AIE molecules are highly luminescent under the excitation of ultraviolet light, and the polymer can provide the mechanical properties required for the composite fiber, the formed polymer / AIE composite luminescent fiber has excellent luminescence and mechanical properties that meet the requirements.

[0072] According to the present invention, the first solvent and the second solvent are each independently selected from at least one of methylene chloride, cyclohexane, phenol, toluene, acetonitrile, chlorobenzene and methyl acetate.

[0073] According to the present invention, in step 4), the conditions of the pre-curing treatment are: the pre-curing temperature is 40-80° C., and the pre-curing time is 5-40 min.

[0074] In the present invention, the pre-curing tr...

preparation example

[0119] use as figure 1 The spinning method shown to prepare luminescent fibers, the specific operation steps are:

[0120] Transfer the spinning solution into a 100ml syringe, and heat the oil bath temperature to 150°C at the same time. The syringe pump extrudes the spinning solution into the oil bath at a speed of 8ml / min., and the spinning solution solidifies rapidly in the oil bath. For fibers, the curing time is 8s, and then the fibers are collected on the winding shaft at a line speed of 2m / min., and finally washed and dried.

Embodiment 1

[0122] Step 1): Prepare aggregation-induced emission (AIE) molecule solution: add 0.006 g of aggregation-induced emission (AIE) molecule II into dichloromethane to obtain aggregation-induced emission (AIE) solution;

[0123] Step 2): Prepare AIE@PDMS component A compound solution: add 1.82g of PDMS component A to the aggregation-induced emission (AIE) molecular solution described in step 1), and stir manually to make it fully mixed and uniform ; Then put the prepared composite liquid into a vacuum drying oven at 40°C for 4 hours to be vacuum-dried;

[0124] Step 3): Prepare AIE@PDMS composite solution: add 0.18 g of PDMS component B to the composite solution described in step 2), stir well to make it evenly mixed, and obtain AIE@PDMS composite solution;

[0125] Step 4): Prepare AIE@PDMS spinning solution: put the AIE@PDMS composite solution described in step 3) into a 60°C oven and heat for 10 minutes, then cool for 30 minutes to form a spinning solution;

Abstract

The invention relates to the field of flexible wearable luminescent devices, in particular to a composite luminescent fiber and a preparation method and application thereof. The composite luminescentfiber comprises a polymer and aggregation-induced emission (AIE) molecules, wherein the curing temperature of the polymer is 0-300 DEG C. According to the composite luminescent fiber, because the AIEmolecules which have high luminescent capability under ultraviolet excitation are contained in the fiber and the polymer is high in softness and stretchability, the formed composite luminescent fiberhas excellent luminescent capability and is highly stretchable.

Description

technical field [0001] The invention relates to the field of flexible wearable light-emitting devices, in particular to a composite light-emitting fiber and its preparation method and application. Background technique [0002] With the advancement of society and technology, flexible wearable devices have received more and more attention. The demand for flexible wearable devices has driven the development of related materials and fabrication techniques. These efforts include integrating functional materials into textiles, or integrating electronic components into human fabrics for special functions such as energy harvesting and storage, multifunctional sensing, communication, and light-emitting displays. Innovations in wearable devices have brought about new concepts in clothing. However, most of the current research reports focus on sensors, energy harvesting and storage, and transistors, among which there are few reports on flexible light-emitting devices. Smart wearable...
