詳細

Tetraethyl orthosilicate(TEOS) is a colorless liquid alkoxide widely used as precursor to deposition of silicon dioxide (SiO2) thin films. It is also utilized in hydrogels, nanoparticle-based drug delivery systems, and chemical crosslinking of polymers.

アプリケーション

Tetraethyl orthosilicate can be used:
  • As an anti-solvent to fabricate efficient perovskite layer for inverted planar solar cells with enhanced power conversion efficiency and reproducibility. TEOS helps to achieve high-quality perovskite films with reduced density of defects, and thus slower carrier recombination.
  • As a sol-gel precursor to synthesize SiO2-TiO2 anti-reflective self-cleaning coatings for solar cells.
  • To fabricate nano silica functionalized crosslinked hybrid membranes for proton exchange membrane fuel cell applications. These membranes have better proton conductivity and thermal stability.
  • To prepare poly(vinylidene fluoride)/TEOS matrix separator to enhance the performance of Li-ion batteries. The separator exhibits excellent electrolyte retention and wettability.

H+-マガジイトの層間化合物形成においてドデシルアミンと相互作用します。混合金属生体活性ガラスの研究に使用されます。
キセロゲル調製の前駆体として広く用いられています。

特徴および利点

  • Excellent adhesion on substrates
  • Uniform film deposition
  • Cross-linker to introduce polymer strands into hydrogel

Magnetism and magnetic materials have been of scientific interest for over 1,000 years. More recently, fundamental investigations have focused on exploring the various types of magnetic materials and understanding the magnetic effects created by electric currents.

Hybrid organic-inorganic sol-gel materials containing silica were first called “ORMOSILs” in 1984.
