일반 설명

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.

애플리케이션

Commonly used as a precursor to prepare xerogel

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.

Will interact with dodecylamine in the formation of intercalation compounds of H⁺-magadiite and used in a study of mixed-metal bioactive glasses.
