Ştefănescu, M. Stoia, O. Ştefănescu, A. Popa, M. Simon, C. Ionescu] Hybrid organic-inorganic materials, silica - polyols (ethylene-glycol - EG; 1,2 propane diol - 1,2PG; 1,3 propane diol - 1,3PG and glycerol - GL), were prepared by a sol-gel process starting from tetraethylorthosilicate (TEOS) and polyols, in acid catalysis. The resulting materials were studied by thermal analysis (in air and nitrogen), FTIR and solid state 29Si-NMR spectroscopy. These techniques evidenced the presence of polyols in the silica matrix both hydrogen bounded and chemically bounded in the silica network. The thermal analysis proves to be the most appropriate technique to evidence the organic chains linked in the matrix network and to follow the thermal evolution of the gels to the SiO2 matrix.
