THIOETHER FUNCTIONALIZED HYBRID MATERIALS (original) (raw)
Thioether-functionalized materials were synthesized by co-condensations of bis [3-(triethoxysilyl)propyl]tetra sulfide (BTPTS) and tetraethoxylsilane (TEOS) in the presence of the nonionic surfactant triblock copolymer poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (EO 20 PO 70 EO 20 ), Pluronic P123. The surfactant was used as a template for improving the porosity of the hybrid gels. In this work we synthesized samples with different amounts of BTPTS in acidic media. The final materials were soaked for 24 hours in ethanol and HCl for removing P123. In this work we investigate structure
