Characterization of sol–gel-derived polyhydridosiloxane pre-ceramic polymer

The polyhydridosiloxane was manufactured by sol–gel method from triethoxysilane. Methanol, hexane and water adsorption/desorption isotherms of the polyhydridosiloxane were measured at 293 K and textural parameters were determined. Fourier transform infrared and inelastic neutron scattering spectroscopic examination of the polyhydridosiloxane along with the quantum chemical simulation have resulted in the theoretically grounded assignment of the spectral bands and evaluation of the theoretical model of the polyhydridosiloxane globule.
