Problems solved by technology

[0003] However, due to the microstructure of graphene, there is a strong tendency to stack between graphene sheets, resulting in poor dispersion in various solvents, adhesives or polymers, and prone to agglomeration. Graphene can be functionalized and modified to enhance the interaction between it and the polymer, so that the graphene can be uniformly dispersed
These problems have affected the excellent properties of graphene (such as mechanical properties, electrical conductivity, thermal stability, etc.)

Abstract

The invention discloses a preparation method of a durable graphene finished fabric. The preparation method is characterized in that a deep eutectic solvent is prepared after a hydrogen bond acceptor compound and a photo-initiated polymerized hydrogen bond donor compound are uniformly mixed, then graphene is added and stirred for dissolution, and a graphene pre-finishing solution is prepared; a photo-initiated polymerizer is added to the pre-finishing solution and stirred for dissolution, and a graphene finishing solution is prepared; the fabric is coated with the graphene finishing solution, the coated fabric is irradiated with ultraviolet light, washed with water at normal temperature and dried in the air, and the durable graphene finished fabric is obtained. The green and environment-friendly deep eutectic solvent is adopted as a finished medium of graphene, the fabric is treated directly by existing fabric equipment, and graphene is applied onto the fabric by finishing. The preparation method can be applied to various fabrics. As a functional durable graphene finished fabric technology, the preparation method has the advantages of being green, pollution-free, low in wastewater discharge, low in price, convenient to operate, suitable for industrial production and the like.

Description

technical field [0001] The invention relates to a preparation method of graphene durable finishing fabric, which belongs to the technical field of graphene durable finishing of textiles. Background technique [0002] At present, graphene has been widely used in the textile field, including graphene fibers, graphene blend fibers, graphene fabrics, antibacterial fabrics, antistatic and conductive fabrics, etc. At present, the methods for preparing graphene-finished fabrics mainly include the following methods: directly coat the surface of the fabric with graphene, add graphene to the high polymer of the fiber raw material and then weave the conductive fabric. Treating graphene onto fabrics can produce excellent antistatic or conductive fabrics. [0003] However, due to the microstructure of graphene, there is a strong tendency to stack between graphene sheets, resulting in poor dispersion in various solvents, adhesives or polymers, and prone to agglomeration. Graphene can be...
