Graphene fabric process is one of the more popular emerging materials at present, it has very excellent mechanical properties, electrical conductivity, thermal stability and transparency characteristics, in clothing, electronic components, energy and other fields have a wide range of application prospects. So, how is graphene fabric produced? Here is a detailed introduction to the production process of graphene fabric.
1. Preparation of graphene
There are many ways to prepare graphene, the most common of which is the mechanical stripping method. The method uses a graphite layer called a graphene sheet to obtain extremely thin graphene by mechanical stripping or chemical reduction. At present, most of the graphene on the market is prepared by chemical reduction method.
2. Preparation of graphene fabric process
The graphene fabric process is usually achieved by combining graphene with textile materials. The process of preparing graphene fabrics can be divided into the following steps:
(1) Graphene dispersion
The prepared graphene was added to a certain solution for dispersion treatment. The commonly used dispersants are DMSO, NMP and DMF.
(2) Textile infiltration
After the graphene dispersion solution is produced, the textile material allows the graphene dispersion solution to fully penetrate into the textile fiber by the way of infiltration.
(3) Heat treatment
The wetted textile is dried, the dispersant in the solution is evaporated, and the graphene is evenly distributed on the surface of the textile.
(4) Pressure treatment
In order to make graphene more firmly bonded to the textile surface, pressure treatment is an essential process link. Some unique mechanical forces, such as hot pressing or embossing machines, are usually used to make the textile surface more closely in contact with graphene.
3. Performance test of graphene fabric process
After the production of graphene fabrics, the performance test is a very critical step, including the thickness of the graphene fabric, light transmittance, electrical conductivity, wear resistance and mechanical strength.
The above is the production process of graphene fabric process, although there are many steps involved, but in fact, it is not difficult to prepare a good graphene fabric, which also lays a good foundation for the application of graphene fabric process in clothing and other fields. In the future, with the continuous improvement of graphene preparation and application technology, it is believed that this material will be more widely used around the world.
