Application
Trimethoxymethylsilane (MTMS) is one of the key precursor for the synthesis of:
- Monolithic silica columns with various skeleton sizes for capillary liquid chromatography.
- Ionogels, where an ionic liquid is confined within silica-derived networks.
- Monolithic silica aerogels via acid-base sol-gel polymerization.
- Hydrophobic, flexible, and ultralightweight silylated nanocellulose sponges for the selective removal of oil from water.

When bicontinuous gels are prepared via sol-gel method in a 2-dimensionally (2D) confined space, the gel skeletons in the vicinity of interface of a mold are elongated perpendicular to the interface. This phenomenon was attributed to the dynamic wetting of
