Abstract
Our recent progress in porous materials based on organic–inorganic hybrids, organic crosslinked polymers, and carbons is summarized. Flexible aerogels and aerogel-like xerogels with the polymethylsilsesquioxane (PMSQ) composition are obtained using methyltrimethoxysilane (MTMS) as the sole precursor. Preparation process and the flexible mechanical properties of these aerogels/xerogels are overviewed. As the derivative materials, hierarchically macro- and mesoporous PMSQ monoliths and marshmallow-like soft and bendable porous monoliths prepared from dimethyldimethoxysilane /MTMS co-precursors have been obtained. Organic crosslinked polymer monoliths with well-defined macropores are also tailored using gelling systems of vinyl monomers under controlled/living radical polymerization. The obtained polymer monoliths are carbonized and activated into activated carbon monoliths with well-defined pore properties. The activated carbon monoliths exhibit good electrochemical properties as the monolithic electrode. Some possibilities of applications for these porous materials are also discussed.
