Embodiment 1

[0029] (1) Use a photosensitive resin 3D printer to print a solid cylinder with a diameter of 1mm and a length of 100mm, and hang it upright.

[0030] (2) 20g of liquid silica gel Ecoflex A component and 20g of Ecoflex B component were added to the beaker to form a uniform liquid polymer, then the container containing the mixture was placed on a 50°C electric hot plate, and magnetically stirred for 1 hour, A homogeneous mixture was obtained.

[0031] (3) Continuously pour the Ecoflex liquid silica gel obtained in step (2) on the outer surface of the cylinder obtained in step (1), until the surface of the cylinder is evenly covered by the Ecoflex liquid silica gel mixture, and the liquid silica gel is no longer directed toward the cylinder. After dripping, the cylinder was left hanging upright and left to cure for 12 hours.

[0032] (4) After the curing is completed, the liquid silica gel obtained in step (3) whose surface has been completely cured is gently taken out from the...

Abstract

The invention discloses a flexible multifunctional metal wire capable of being bent at will and a preparation method thereof, and belongs to the technical field of multifunctional materials.The preparation method comprises the steps that a solid cylinder is prepared through a photosensitive resin 3D printing technology, a liquid polymer is poured on the outer wall of the solid cylinder, standing is conducted, and after the polymer is solidified and formed, demolding is conducted, and the flexible multifunctional metal wire capable of being bent at will is obtained. A flexible shell is obtained; liquid metal is injected into the flexible shell, the two ends of the flexible shell are closed, and the multifunctional metal wire capable of being bent at will is formed. The prepared multifunctional metal wire can be stretched and bent at will, has good anti-fatigue performance, not only can be used for common wires, but also can be woven in wearable equipment such as fabrics and the like, and has wide application prospects in the fields of medical treatment and health care.

Description

technical field [0001] The invention belongs to the technical field of multifunctional materials, in particular to a flexible multifunctional metal wire that can be bent at will and a preparation method thereof. Background technique [0002] The traditional metal wires are hard in texture, strong in rigidity, and have poor tensile and bending resistance, thus limiting their application. Liquid metal is a kind of amorphous, flowable liquid metal, and has many similarities with simple non-metallic liquids, which solves the shortcomings of traditional metals such as strength and strength. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems of poor bending resistance and single function of traditional metal wires, a flexible multifunctional metal wire with good stability and arbitrary bending is provided. [0004] A first aspect of the present invention provides a method for preparing a flexible multifunctional metal wire that can be ben...
