Paper Abstract

The D2O absorption spectra adsorbed on the nanoporous airgel SiO2 walls in the spectral range 4200 ... 5400 cm-1 are recorded. Two types of sample with pores of 60 nm wide - the nitrogen gas-treated and untreated airgels were examined. The untreated sample was prolonged evacuation and filling by the D2O saturated vapor. The nitrogen gas-treated sample was short-time pumping, accompanied by treatment with dry nitrogen, and re- lapping by the saturated vapor. As a result, the recorded absorption spectra were shown the changes the hydrophilic properties of the nanopores walls by modernity surface in the presence of nitrogen.
