Example Embodiment
[0121] In the second aspect of the present invention, the above-mentioned The method for preparing the fabric material with the modified layer is described in The terms used in Have the same meaning or definition. The method includes the step of forming a modified 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, the fabric as the base layer may be subjected to surface pretreatment before forming the modification layer. The pretreatment can generate or have a positive charge on the surface of the base fabric layer, which can form a bond with the negatively charged one-dimensional and / or two-dimensional nano-conductive material in the subsequent processing, which helps the modified layer and The base layer is more reliable and firmly bonded.
[0124] For surface pretreatment methods, plasma surface treatment and / or chemical modification methods can be use...

[0146] Example
[0147] Examples of the present invention will be described below, but the present invention is not limited to the following examples.
[0148] One-dimensional nano conductive materials
[0149] Nano silver wires (AgNWs, average diameter is 50nm, average length is about 150μm);
[0150] Two-dimensional nano conductive materials
[0151] MXene nanosheets (which remove Ti by using LiF / HCl solution 3 AlC 2 The aluminum layer is then prepared by ultrasonic layering, and its thickness does not exceed 3.6nm);
[0152] Fabric as a base
[0153] Silk, cotton, nylon, wool;
[0154] Process
[0155] The silk substrate is treated with oxygen plasma and polyethyleneimine (PEI) solution in sequence to introduce sufficient polar (positive charge) groups to promote the loading of conductive nanomaterials. Then, by using a vacuum-assisted layer-by-layer assembly method, the treated silk was alternately sprayed with MXene nanosheets and AgNWs (nano silver wires) to construct a highly co...
