Organic-inorganic hybrid materials have been synthesized by the sol-gel method, using tetraethyl orthosilicate TEOS), poly(ethylene oxide) (PEO), net-polyacrylic-inter-net-polysiloxane, butyl acrylate, ethyl acetoacetate, tetrahydrofuran, acetonitrile and LiClO4 precursors and additives. Mass fractions of the organic additions in the gels were of ca 35-40 mass%. The hybrid materials obtained were amorphous, colourless, transparent or translucent, with room temperature ionic conductivities in a range of 10-4-10-3 omega-1cm-1. The results of scanning electron microscopy equipped with energy dispersive X-ray spectroscopy (SEM/EDX), Fourier transform infrared spectroscopy and 29Si MAS Nuclear Magnetic Resonance analysis have revealed [SiO4] tetrahedrons polycondensation strongly influenced by organic precursors and chemical bonding between organic and inorganic parts of the gels obtained.
