The research covered most of the recent scientific research related to strengthening the natural rubber and improving its physical properties. The swelling properties played a substantial role in decreasing the efficiency of the elastomer compounds as a result of immersing or contacting these compounds with organic solvents. Using nanoparticles for inorganic fillings is absolutely essential with a view to expanding the industrial applications of natural rubber Nano-composites. The research covered the latest methods that researchers have used to reduce rubber swelling to the lowest levels. The paper discussed the relationship between swelling properties and mechanical, electrical, curing, and morphology properties. The research also discussed the relationship between swelling properties and the concentration of the filter used to harden the rubber matrix, the swelling capacity, and the type of Nano-composite. All results, which discussed by previous studies showed that improving the thermal, electrical and mechanical properties of the Nano-composites of natural rubber leads to a reduction in the swelling problems of the natural rubber compound, and that selecting or modifying the properties of the filler material gives encouraging and strong results towards reducing the rates of swelling.
