Chemically modified sepiolite was used as filler in silica based elastomeric composites. The sepiolite was modified through the reaction with silica (nano) particles from silanes such as TEOS and TESPD. Characterization of silica (nano) particles and sepiolite was performed by means of dynamic light scattering, thermogravimetric, elemental analysis, infrared spectroscopy and field emission scanning electron microscopy.
