Embodiment 1

[0081] Weigh 1 g of graphene fiber powder and 1 g of silver nanowire powder and redisperse them in 500 mL of deionized water containing 10 mg / mL CTAB and 2 mg / mL epoxy resin to prepare a graphene dispersion for use. Cut a woven or knitted fabric with a size of 25×25cm and a thickness of 1mm and attach it to the substrate of the coater, pour 100mL of the above dispersion into the pusher of the coater, and adjust the speed of the coater to 5cm / s. Complete the uniform coating of the graphene fiber and silver nanowire mixture, and dry at 60°C for 2 hours to obtain the graphene fiber fabric. After the surface is coated with a PU and PDMS waterproof coating with a thickness of 10 μm, a fast electric heating graphene fiber fabric is made after externally connecting wires, a voltage regulator, and a power supply.

Embodiment 2

[0083] Weigh 2 g of graphene fiber powder and 1 g of copper nanowire powder and redisperse them in 500 mL of deionized water containing 20 mg / mL CTAB and 3 mg / mL epoxy resin to prepare a graphene fiber dispersion for use. Cut a woven or knitted fabric with a thickness of 2mm and a size of 25×25cm and attach it to the substrate of the coater, pour 200mL of the above dispersion into the pusher of the coater, and adjust the speed of the coater to 6cm / s. Complete the uniform coating of the graphene fiber and copper nanowire mixture, and dry at 50°C for 3 hours to obtain the graphene fiber fabric. After the surface is coated with a PU and PDMS waterproof coating with a thickness of 10 μm, a fast electric heating graphene fiber fabric is made after externally connecting wires, a voltage regulator, and a power supply.

Abstract

The invention provides a preparation method for a quick-electric-heating graphene fabric which is even in heating and better in flexibility and comfort. A graphene fiber and a silver nanowire or a gold nanowire or a copper nanowire are adopted for replacing a traditional heating resistance wire, and the graphene fabric is more even in heating, small in resistance, low in energy consumption and better in safety performance; graphene has better flexibility, so that the integrity and comfort of the fabric are improved, and the whole preparation method is simple and economical.

Description

technical field [0001] The invention relates to the technical field of electric heating fabrics, in particular to a method for preparing fast electric heating graphene fabrics. Background technique [0002] Although in the cold season, people can add warm clothing to prevent cold and keep warm, but the passive heating method still has its own defects in extremely cold conditions and cannot actively provide heating. The development of new active heating clothing has become one of the development trends of functional clothing. At present, most of the heating clothes used in the market are built-in conductive carbon fibers, which generate heat through electric heating. The disadvantage is that the spot heating method is uneven; the resistance wire has a large resistance value, slow heating, and high energy consumption; it is easy to break and has a low safety factor; The resistance wire is relatively hard, and the comfort of the human body is poor. In order to find a material...
