Résumé: Polysulfide–functionalized mesoporous were synthesized by using co–condensations of tetraethoxylsilane(TEOS) and bis[3-(triethoxysilyl)propyl]tetra sulfide (BTPTS) in the presence of nonionic surfactant triblock copolymer poly(ethylene glycol)-block-poly(propylene glycol)-block- poly(ethylene glycol) (EO 20PO 70EO 20) Pluronic P123. The surfactant was used as template for improving the porosity of the hybrid gels. In this work we synthesized samples with different BTPTS amounts in acidic media. The final materials were soaked for 24 hours in ethanol and HCl for removing of P123. In this work we investigate the materials structure before and after extraction of the surfactant and the functional group amount incorporated in the silica framework. For this aims we used thermo gravimetric analysis (DTA/TG), Fourier–transform infrared spectroscopy (FT-IR), and elemental analysis.
