The GO was dispersed in cetyltrimethylammonium bromide solution (20 wt%) and ultrasonicated for 0.5 h, followed by mechanical stirring at 25[degrees]C for 24 h.
We prepared buffer containing citric acid (40 mmol/L) and cetyltrimethylammonium bromide (0.8 mmol/L), adjusted to pH 4.4 with [gamma]-aminobutyric acid (2), filtered and sonicated for 0.5 min before use.
Specifically, the present invention provides a rubber composition comprising a rubber composition and hydrated silica, wherein "CTAB" ([m.sup.2]/g) as specific surface area by cetyltrimethylammonium bromide adsorption and "IB" as ink bottle-shaped micropore index, of the hydrated silica, satisfy a specific relationship and "weight loss on ignition" (mass %) as weight loss when the hydrate silicate is heated at 750[degrees]C for three hours and "weight loss on heating" (mass %) as weight loss when the hydrate silicate is heated at 105[degrees]C for two hours satisfy a specific relationship.
