Description

technical field [0001] The invention belongs to the technical field of rubber material preparation, and in particular relates to a graphene-modified rubber material with high bending strength. Background technique [0002] Rubber: A highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. [0003] The word rubber comes from the Indian word cau-uchu, which means "tearful tree". Natural rubber is made by coagulating and drying the latex that flows out from Hevea clover tree tapping. In 1770, British chemist J. Priestley discovered that rubber can be used to erase pencil writing. At that time, the material for this purpose was called rubber, a...
