Description

technical field [0001] The invention belongs to the field of composite fiber preparation, in particular to a graphene composite PVA fiber and a preparation method. Background technique [0002] Polyvinyl alcohol is a polymer with excellent performance and a wide range of uses. The high-performance fiber prepared from it has excellent corrosion resistance, weather resistance and good bonding performance with the substrate interface. It is the most developed among synthetic fibers. Promising asbestos substitute materials are widely used in the construction industry, and can also be used as tire cords, industrial fabrics, high-performance ropes, plastics, and rubber reinforcements, etc., with great market potential. [0003] However, since polyvinyl alcohol is a crystalline polymer, the molecule contains a large number of hydroxyl groups, which can form a large number of intramolecular and intermolecular hydrogen bonds, making its melting point as high as 220-240°C, but its dec...
