| 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. |
