The dependence of structural properties on the preparation parameters was investigated by solid state29 Si MAS NMR, high-resolution TEM, low temperature N2–adsorption/desorption isotherms, thermo-gravimetric analysis (TGA–DTA), Fourier transform infrared spectrophotometry (FT–IR) and water contact angle measurement. Characterization results showed that the hybrid material prepared under optimal conditions possesses stable framework structure and developed porosity with high specific surface area and pore volume of 1076 m2/g and 1.03 cm3/g, respectively. %K composites %K hybrid material %K characterization %K poly(methylhydrogen)siloxane %K bridgedorganosilica
