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.
