Abstract: A clay compound modified with a tetra sulfide group, a rubber/clay nanocomposite containing the same, and methods for preparing them are provided to show excellent mechanical properties including tensile strength, elongation at break, tear strength and heat stability while maintaining flexibility. A clay compound is modified with a tetra sulfide group and particularly, is prepared by a method comprising the steps of: admixing a silane compound containing a tetra sulfide group to a water-soluble solvent and hydrating the admixture with an appropriate acid; and admixing clay to the resulting hydrated silane compound solution, followed by stirring. A rubber/clay nanocomposite contains the clay compound modified with the tetra sulfide group, and particularly, is prepared by a method comprising the steps of: mixing the clay compound modified with the tetra sulfide group, a rubber and a cross-linking agent, followed by stirring; and drying the resulting solution, and then heating the solution under a pressure to be cured. Further, the rubber is a silicon rubber which is poly dimethyl siloxane.
