“…To achieve the goal of sustainable development in rubber industry, many new fillers have been employed. Among them, the abundant clays such as kaolinite [ 21 , 22 ], montmorillonite [ 23 , 24 ], hydrotalcite [ 25 , 26 ], vermiculite [ 27 , 28 ], sepiolite [ 29 , 30 ], and illite [ 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ] have drawn great attention because of their low production price and carbon footprints. The reinforcement effect of these clays on rubber matrix is, however, not satisfactory.…”
