Description
Technical Field
The invention relates to the technical field of textile materials and flexible electronic materials, in particular to a textile material containing liquid metal and a preparation method thereof.
Background
With the development of flexible electronics and wearable devices, elastic conductors have attracted more and more attention due to their excellent stretchability and comfort. The liquid metal material is a conductive material which is liquid at room temperature, has metal conductivity and fluidity, and therefore has good application value in flexible electronic devices, such as flexible electrodes for liquid metal, flexible sensors and the like.
Recently, there has been reported the application of liquid metal to the field of textile garments to realize functional garments, smart garments, and the like. However, how to combine the liquid metal with the textile material to prepare the textile material with safe and comfortable wearing, stable performance and high preparation success rate is a technical problem for those skilled in the art.
CN206024138U discloses a liquid metal cloth, which comprises a first textile layer, a second textile layer, an insulating layer, a liquid metal and a control module, wherein the insulating layer has a hollow enclosed space, and the hollow enclosed space of the insulating layer is filled with the liquid metal. This patent document discloses a method for forming a bladder-shaped insulating layer by joining two heat-conductive insulating films, and encapsulating a liquid metal in the bladder-shaped insulating layer, the method comprising: firstly, uniformly mixing Polydimethylsiloxane (PDMS) and a silica gel curing agent in a mass ratio of 10:1, then uniformly coating the mixed solution on the surface of glass, heating the glass in a heating box at 75 ℃ for one hour, placing a plastic or metal mask plate on the PDMS mixed solution, taking out the PDMS mixed solution after the PDMS mixed solution is solidified, wherein grooves appear on the surface of the PDMS mixed solution, and forming a lower-layer insulating film; then, taking down the mask plate, uniformly spraying the liquid metal on the lower insulating film by using a liquid metal spray gun, and uniformly spreading the liquid metal along the grooves of the lower insulating film to obtain a liquid metal layer; and placing the control module at a position corresponding to the liquid metal, uniformly coating the PDMS mixed solution on the lower insulating film sprayed with the liquid metal, then placing the PDMS mixed solution in a heating box at 75 ℃ to heat for one hour, and forming an upper insulating film after the PDMS is solidified, thereby completing the encapsulation of the liquid metal layer and the control module between the two insulating films.
The liquid metal cloth disclosed in the above patent document has the following problems:
(1) the above patent documents only disclose the first textile layer and the second textile layer for wrapping the insulating layer and the preparation method of the bladder-shaped insulating layer for encapsulating the liquid metal, but do not disclose how the insulating layer having the hollow closed space is combined with the first textile layer and the second textile layer.
(2) In the preparation process of the capsule-shaped insulating layer for packaging the liquid metal, the plastic or metal mask plate is placed on the PDMS mixed liquid, and the PDMS mixed liquid is taken out after being solidified to obtain a groove for containing the liquid metal. However, in actual practice, this method has the following problems:
(a) after the PDMS mixed liquid is solidified, the plastic or the metal mask is difficult to take out of the solidified body, so that a groove is difficult to obtain, or the shape of the obtained groove is different from the expected shape of the groove;
(b) in order to improve the workability of taking out the plastic or metal mask from the solidified body, the three-dimensional size of the mask cannot be too small, and therefore the three-dimensional size of the groove obtained by this method is large, and particularly, the thickness and width thereof are large, at least 500 μm or more. However, in practical application, the thickness of the liquid metal in the fabric is preferably smaller, so that the wearability and comfort of the fabric can be improved; on the other hand, when the thickness of the liquid metal is smaller, the influence of the liquid metal when the fabric is subjected to external forces such as folding, kneading, squeezing and the like in practical application is smaller, so that the performance stability of the fabric is improved.
(3) The method has poor operability and low preparation success rate in practical application.
