The invention relates to the use of nanocarbon (carbon nanotubes and/or carbon nano fibers) in the preparation of reinforced natural rubber. It is an object of the invention to provide a simple way to disperse nanocarbon in rubber so as to obtain good physical and mechanical properties, such as hardness, modulus and/or tensile strength. In order to achieve these objects, the invention provides a natural rubber composition comprising 5 parts per hundred of rubber (pphr) or less of nanocarbon, wherein the nanocarbon has not been subjected to an acid treatment before incorporation into the rubber composition. Furthermore, the invention also provides a method of making a natural rubber composition comprising nanocarbon, wherein the method comprises the following steps: (i) providing a dispersion of nanocarbon in a aqueous medium, and (ii) combining the dispersion of nanocarbon with a natural rubber latex; and wherein the nanocarbon is not subjected to an acid treatment before incorporation into the rubber composition and the natural rubber composition comprises 5 pphr or less of nanocarbon. |
