Electronic textiles, also known as smart garments, smart clothing, smart textiles, or smart fabrics, are fabrics that enable digital components such as a battery and a light (including small computers), and electronics to be embedded in them. Smart textiles are fabrics that have been developed with new technologies that provide added value to the wearer. Pailes-Friedman of the Pratt Institute states that "what makes smart fabrics revolutionary is that they have the ability to do many things that traditional fabrics cannot, including communicate, transform, conduct energy and even grow".
An electronic textile based on laser-activated printable conductive ink and a method of making the same
The application relates to the technical field of electronic fabrics, in particular to an electronic fabric based on laser-activated printable conductive ink and a preparation method thereof. Bismuth, indium and tin are mixed to obtain a mixture, the mixture is smelted to completely melt, and a molten alloy is obtained; the molten alloy is mixed with boiling water and ultrasonically treated to obtain an alloy dispersion liquid; the alloy dispersion liquid is centrifuged to obtain alloy particles which are dried and then mixed with a binder solution and stirred to obtain an alloy particle and binder solution composite ink; the ink is then patterned on a fiber pad in a stencil printing mode, and after activation, an electronic fabric is obtained. By combining an electrospun polyimide nanofiber base material and a laser-sintering-activated printable bismuth alloy conductive ink, the prepared electronic fabric has high flexibility, high air permeability and high conductivity, and the square resistance can reach 0.5 omega / D.
