应用

Tetraethyl orthosilicate (TEOS) is an oxygen containing precursor of Si used for the deposition of:
  • Si oxide
  • Oxycarbide
  • Doped silicate
  • Silanol
  • Siloxane polymer
  • Organosilicon thin films

The films can be deposited at low temperatues (<250 °C). TEOS is also used to deposit mesoporous and nanoporous thin films of silica. These porous films can be doped during deposition to further enhance their properties.

Macroscopic inorganic porous beads are imbibed with a "porous molecular additive" by simple solution processing techniques, resulting in controllable loading and increased surface area. The porous additive consists of soluble organic cage molecules that precipitate as microporous crystals when solutions
