Embodiment 1

[0059] Preparation of modified polyacrylonitrile fibers

[0060] (1): Prepare a mixed impregnation solution containing graphene C, including silane coupling agent monomer, nano silver wire, graphene C and deionized water:

[0061] The concentration of silver nanowires is 2mg / mL,

[0062] The concentration of silane coupling agent monomer is 100mg / mL,

[0063] The concentration of graphene C was 10 mg / mL.

[0064] (2): The polyacrylonitrile fiber is immersed in the above impregnation solution containing graphene C, and the immersion time is 2 hours.

[0065] (3) Take out the impregnated polyacrylonitrile fibers, and irradiate the polyacrylonitrile fibers with an electron accelerator.

[0066] The irradiation dose rate is 50KGy / h, and the irradiation time is 1h.

[0067] Performance tests were performed on irradiated polyacrylonitrile fibers.

Embodiment 2 to 5

[0069] The difference between embodiments 2 to 5 and embodiment 1 is only that the radiation dose rate is different, and all the other steps and parameters are the same. The radiation dose rates of embodiments 2 to 5 are respectively: 30KGy / h, 60KGy / h, 80KGy / h, 100KGy / h.

Abstract

The invention provides a graphene modified material as well as a preparation method and application thereof. The preparation method of the graphene modified material comprises the following steps thata substance to be steeped is steeped in steeping liquid; then, the substance to be steeped is taken out for irradiation; the substance to be steeped comprises fiber, yarns or fabrics; the steeping liquid is mainly prepared from a graphene material, a cross-linking agent, a nanometer conducting metal wire and water. The preparation method solves the problem that the conducting performance cannot be improved since graphene and fiber and other products cannot be effectively crosslinked; the graphene modified material prepared by the method has the advantages of high electric conductivity, lightweight, antistatic performance, wide application range and the like.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a graphene modified material and its preparation method and application, in particular to the preparation method of conductive fibers, yarns or fabrics. Background technique [0002] Conductive fiber has good conductivity and durability, especially in low humidity, it still has good durable antistatic property. When the conductive layer reaches a certain thickness or the conductive component reaches a certain proportion, it has excellent electromagnetic shielding function. Therefore, in It has great uses in industrial and civil fields, such as conductive mesh and conductive work clothes in electronics and electric power industries, electric heating clothes and electric heating bandages in medical industry, electromagnetic shielding covers in aviation, aerospace, and precision electronics industries, etc. The antistatic mechanism of conductive fibers is to generate corona discharg...
