Embodiment 1

[0028] Example 1: A coaxial needle / 3D printing method for preparing personalized smart patterns

[0029] This embodiment provides a coaxial needle / 3D printing method for preparing personalized smart patterns, including:

[0030] (1) Preparation of slurry

[0031] The insulating cortex slurry is a slurry composed of water and silk fibroin, wherein the mass concentration ratio of the silk fibroin is 25%.

[0032] The conductive core layer slurry is a slurry composed of water, carbon nanotubes and a polyvinyl alcohol thickener, wherein the mass concentration of the carbon nanotubes is 5%, and the mass concentration of the polyvinyl alcohol thickener is 30%.

[0033] (2) Connect the coaxial printing needle to the 3D printing mobile terminal for printing to obtain personalized patterns

[0034] Specifically: the configuration of the coaxial needle is as follows figure 1 As shown in a, the needle of the outer layer is connected to the syringe equipped with silk fibroin slurry, an...

[0036] Example 2 Characterization of three-dimensional skin-core structural fibers and personalized patterns of their composition

[0037] The three-dimensional skin-core structure fiber prepared in Example 1 is as follows: figure 2 shown. figure 2 a is the scanning electron microscope image of the three-dimensional skin-core structure fiber. The prepared three-dimensional skin-core structure fiber can exist stably on the fabric, and it is detected by the optical microscope ( figure 2 b) Observation shows that the core layer of carbon nanotubes is tightly covered by the outer layer of silk fibroin, forming a coaxial skin-core fiber structure. figure 2 c is the cross-section of the skin-core structure fiber. It can also be observed that the core layer is tightly wrapped, and the enlarged view of the core layer shows that the contact between carbon nanotubes constitutes its conductive channel.

Abstract

The invention relates to a skin-core structure fiber intelligent pattern and a printing method and application of the skin-core structure fiber intelligent pattern. The printing method of the skin-core structure fiber intelligent pattern comprises the steps that (1) skin-layer fiber slurry and core-layer fiber slurry are prepared; (2), the skin-layer fiber slurry and the core-layer fiber slurry are input into a coaxial printing needle and then connected with a 3D printing mobile terminal, printing is performed on a substrate according to a preset pattern, and the skin-core structure fiber intelligent pattern can be obtained. A complex three-dimensional skin-core structure which cannot be obtained by an ordinary planar printing technology such as ink-jet printing and silk-screen printing can be realized, custom-made pattern fabrication can be realized, and the prepared structure and pattern can be widely applied to wearable intelligent electronic devices.

Description

technical field [0001] The invention relates to the field of wearable intelligent electronic device manufacturing, in particular to a skin-core structural fiber personalized intelligent pattern printed by coaxial needles and 3D printing technology, as well as its printing method and application.
