Fig. 1. (a) SEM micrographs of [Si]3.5 hybrid aerogel series, with and without coupling agent at different magnifications, (b) pure SF aerogel at different magnifications, (c) TEM micrographs of EMT-10-SF-40 aerogel hybrids, (d) SEM micrographs [Si]17.5 hybrid aerogel series with and without coupling agent at different magnifications, (e) SF free PMSQ (EM) and carboxylic-acid-modified PMSQ aerogels, and (f) TEM micrograph of an individual secondary particle of sample EMT-10 (i) and after sectioning a similar particle by ultramicrotome approach (ii), (g) the representative PMSQ–SF aerogel hybrids in two different shapes.
