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.

Organic-inorganic hybrid materials were synthesized by controlled hydrolysis of tetraethoxysilane (TEOS), methyltrimethoxysilane (MTES), synthetic wollastonite powders and polydimethylsiloxane (PDMS) in an ethanol solution. Aerogels were prepared from acid hydrolysis of TEOS and MTES with different volume ratio in ethanol, followed
