TEXTURAL AND STRUCTURAL STUDIES OF AEROGELS BY RAMAN SCATTERING AND THERMOPOROMETRY

J. Rousset , A. Boukenter , Bernard Champagnon , E. Duval , J. Quinson , M. Chatelut , J. Dumas , J. Serughetti

Experimental results on the structure of base-catalysed aerogels obtained from low frequency Raman scattering and thermoporometry are presented. The size of textural units or beads and of mesopores are determined. These results are in agreement with a fractal structure only in the textural units.
