Problems solved by technology

It is worth noting that the introduction of hydrophobic coatings still has concerns that it may affect the original properties of the fabric such as breathability and comfort.
[0009] It can be seen that although the existing technology has explored to a certain extent in terms of endowing fabrics with specific properties, there is still room for further exploration and improvement in terms of how to take into account the original excellent properties of fabrics and endow new characteristics.

preparation example Construction

[0121] In the second aspect of the present invention, the preparation method of the fabric material with the modified layer described in the above is provided, and the term used in the has the same meaning as that of the meaning or definition. The method includes the step of forming a finishing layer on at least one side of the base layer by a layer-by-layer assembly method.

[0122] surface pretreatment

[0123] In some specific embodiments of the present invention, before forming the modification layer, the surface pretreatment of the fabric as the base layer may be performed first. The pretreatment can make the surface of the base fabric layer generate or have a positive charge, which can form a bond with the negatively charged one-dimensional and / or two-dimensional nano-conductive material in the subsequent treatment process, which helps the modification layer and The base layer is more reliable and firmly bonded.

[0124] For surface pretreatment methods, plasma s...

Abstract

The invention relates to a fabric material and a production method thereof. The fabric material comprises a substrate layer and modification layers formed on at least one side of the substrate layer,wherein the substrate layer comprises a fabric layer, each modification layer comprises a one-dimensional nano conductive material and a two-dimensional nano conductive material, the surface of each modification layer is a layer formed by the two-dimensional nano conductive material, and the two-dimensional nano conductive material is selected from two-dimensional transition metal carbon / nitrogencompound. The two-dimensional nano conductive material and the one-dimensional nano conductive material are assembled on the substrate layer, nanowire contact resistance is lowered, excellent electromagnetic shielding performance is achieved, the aging spontaneous hydrophobicity and humidity responsiveness of the two-dimensional conductive material on porous fabric allow the electronic fabric to have hydrophobicity and a humidity monitoring function. The multifunctional fabric is widely applicable to fields such as intelligent garments, humidity sensors and electromagnetic shielding.

Description

technical field [0001] The invention belongs to the field of textile materials, and in particular relates to the preparation of a multifunctional electronic fabric, especially a fabric assembled layer by layer of one-dimensional nanomaterials and two-dimensional nanomaterials and a preparation method thereof. Background technique [0002] Flexible and conductive textiles are of great potential commercial interest due to their potential applications in the production of portable electronics and multifunctional wearable textiles. Such applications could be of great value in energy storage, electromagnetic interference (EMI) shielding, human health monitoring, personal thermal management, and human-computer interaction, for example. [0003] Generally, those commercially available textiles with tunable composition and texture are considered ideal substrates for the design and fabrication of scalable and cost-effective e-textiles. One of the challenges, however, is how to recon...
