Description
Technical Field
The invention relates to the technical field of conductive fabrics, in particular to a high-conductivity fabric based on graphene conductive slurry and a coating process thereof.
Background
In recent years, with the rapid development of mobile internet and intelligent terminals, wearable electronic devices have shown great market prospects. The flexible wearable electronic sensor serving as one of the core components has become a focus of attention of people due to the characteristics of wide-range sensitivity, response time, portability, use comfort, multifunctional integration and the like of the device, and researches and developments on the flexible wearable electronic sensor by researchers at home and abroad are stimulated. The advantage of the flexible sensor makes it have very good application prospect, including in medical electronics, environmental monitoring and wearable etc. field. For example, in wearable aspects, flexible electronics are easier to test for relevant parameters of the skin because the body of a person is not flat.
As is well known, graphene is a two-dimensional material formed by closely stacking hexagonal carbon atom structures, and a two-dimensional crystal with a thickness of only one carbon atom has a stable six-membered ring structure. The graphene has a structure with a perfect large pi conjugated system and a thinnest monolayer atom thickness, so that the graphene has very excellent and unique physical properties and chemical properties of light, electricity, magnetism, machinery and the like. It is the material known by man to be the lightest in weight, the best in toughness, the highest in light transmittance, the best in electrical conductivity, and is widely used because of its superior properties. Based on the characteristics, the graphene can be applied to the preparation of wearable sensors.
However, the graphene powder has a problem of non-uniform dispersion in the process of preparing the conductive paste, so that the graphene in the paste is agglomerated, thereby resulting in low conductive performance and thermal response performance. In order to solve the problem of dispersibility, those skilled in the art oxidize graphene to form graphene oxide, and use a large amount of surfactant and dispersant to help the graphene powder to be uniformly dispersed. However, for the conductive paste, the surfactant and the dispersant do not participate in the conduction by themselves, which may affect the electrical properties and stability of the electronic device during use.
Due to the fact that the graphene is of a two-dimensional (2D) periodic honeycomb lattice structure composed of carbon six-membered rings, the graphene has a repulsive effect on an absolute ethyl alcohol solution, and the graphene is poor in dispersibility in the absolute ethyl alcohol solution, so that the graphene is difficult to be uniformly coated on fabrics such as non-woven fabrics on one hand, and the graphene coating is easy to fall off due to poor adhesion even after the graphene is attached to the non-woven fabrics on the other hand, and therefore the conductivity, the water washing resistance and the thermal responsiveness are relatively poor.
Patent CN 104873200A discloses a flexible sensor for detecting human body movement and a preparation method thereof, wherein the flexible sensor comprises a flexible polymer layer and an electrode layer, and the flexible polymer layer is disposed on the electrode layer. In this patent, the flexible polymer layer and the electrode layer are respectively charged with triboelectric charges having the same charge amount but opposite polarities after contact friction, and the electric potential of the electrode layer is changed by applying stretching and retracting of the flexible polymer layer, thereby driving electrons to flow back and forth between the electrode layer and the ground electrode to generate an electric signal. The flexible sensor can be used for detecting the movement of a human body, has the advantages of simple preparation method, low cost, high detection precision and the like, and has great application prospect in the fields of medical diagnosis and treatment, physical exercise, safety protection and the like. However, the flexible sensor in the patent is formed by layering a flexible polymer layer and an electrode layer, namely, the flexible polymer layer is arranged on the electrode layer, and then a lead is connected on the electrode layer to obtain the flexible sensor, and the layering phenomenon is easy to occur between the two layers. And the final detection accuracy and the thermal response performance of the flexible sensor are influenced by the tight combination degree between the two layers, so that the flexible sensor prepared by the patent has poor stability and influences the detection accuracy and the thermal response performance.
Also, for example, patent CN 107298924A discloses a graphene conductive paste, a preparation method and an application method thereof, which comprise the following raw materials in parts by weight: comprises 0.5 to 15.0wt percent of few-layer graphene; 0.1 to 5.0 weight percent of dispersant; 80-99.4wt% of diluent; 10-40.0wt% of organic resin. This patent is through the screening of earlier stage to the dispersing agent, in the mixing process of graphite alkene powder and diluent, graphite alkene can disperse in the diluent more easily, and the dispersion stability that obtains is good, adds the selected dispersing agent and cooperates its adopted technology of adoption to promote the peeling off of graphite alkene in the diluent, replaces partial solvent with partial resin in thick liquids and makes the solid content of thick liquids increase, improves thick liquids stability, prevents the back of graphite alkene and folds, can provide fine compatibility for the application in later stage again. Although this patent addresses the uniformity of graphene in the slurry and replacing part of the solvent with part of the resin increases the solids content of the slurry, solving the compatibility problem for later applications. Specifically, the dispersing agent and the diluent are mixed firstly, and then the graphene powder is added to realize uniform mixing of the graphene powder. However, since graphene powder is used, and the graphene powder needs to be wetted first and then dispersed, when the powder is added into a solution, the dispersion is slow, and a phenomenon of stacking and agglomerating of part of the powder may occur in the wetting process. Secondly, although the patent also adds a dispersant to assist the dispersion, the dispersant is added when the powder is added, and stacking agglomeration of graphene particles may already occur. When the agglomeration phenomenon occurs and then the dispersion is carried out, the dispersion effect is greatly reduced, so that the graphene powder has poorer dispersion in the slurry, and the conductive performance and the thermal response performance are reduced.

A coating process of a highly conductive fabric based on graphene conductive paste is characterized in that the graphene conductive paste is transfer coated on a flexible fabric through a screen printing process. The flexible fabric is firstly placed between the printing table and the silk screen, and pressure is applied to the fabric through the weight of the printing table, so that the flexible fabric is flatly unfolded.

Example 3
The same parts as those in embodiments 1 and 2 are not described again, except that the flexible substrate in this embodiment is a flexible fiber, and another coating method of the flexible fiber specifically includes unwinding the flexible fiber, drawing the flexible fiber through a drawing device at a speed of 10 m/min through a water tank filled with graphene conductive slurry, heating and drying at 80-120 ℃ for 2-3min, collecting the coated graphene conductive fiber by a winding machine for later use, and finally spinning the graphene conductive fiber coated with the graphene conductive slurry into a fabric by a spinning technology to obtain the highly conductive fabric.
