Applications: Application Commonly used as a precursor to prepare xerogel Tetraethyl orthosilicate can be used: 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 XLogP value of 1.57 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Tetraethoxysilane. With a topological polar surface area (TPSA) of 36.9 Ų, Tetraethoxysilane exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Tetraethoxysilane has 0 hydrogen bond donor(s) and 4 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
