一般描述
正硅酸乙酯（TEOS）是正硅酸的乙酯，是最容易获得的一种硅源。它主要用作硅聚合物的交联剂和硅薄膜制备的前体。
应用
- Effects of Tetraethyl Orthosilicate (TEOS) on the Light and Temperature Stability of a Pigment from Beta vulgaris and Its Potential Food Industry Applications: This study explores how TEOS can enhance the stability of natural pigments from beets, suggesting potential for improved food colorants (GA Molina et al., 2014).
- Characterization of Chemical Vapor Deposited Tetraethyl Orthosilicate based SiO2 Films for Photonic Devices: The study details the use of TEOS in the production of silicon dioxide films for enhanced photonic device performance (J Kotcharlakota et al., 2016).
- Comprehensive performances of carbon nanotube reinforced foam concrete with tetraethyl orthosilicate impregnation: Research indicates significant enhancements in the structural properties of foam concrete, essential for building technology (J Luo et al., 2017).
- Mesoporous bis (trimethoxysilyl) hexane (BTMSH)/tetraethyl orthosilicate (TEOS)-based hybrid silica aerogel membranes for CO2 capture: Highlights the development of innovative aerogel membranes for effective CO2 capture, contributing to environmental management strategies (YF Lin et al., 2016).
