The preparation and structural characterization of ambient-dried porous methylsilicone matrix doped with SiO2 powder

► SiO2-doped methylsilicone porous monoliths were prepared by a facile process. ► The well dispersion of SiO2 nanoparticles in methylsilicone matrix was achieved. ► The thermal stability of SiO2-doped methylsilicone monoliths was enhanced.
