aIn this work, a simple sol–gel process has been used to synthesize an alumina nanocrystalline powder using aluminum isopropoxide as raw materials. In the synthesis, is opropyl alcohol (C3H7OH), polyethylene glycol (PEG1000) and HNO3 are used as a solvent and a complexing agent 在这工作...

As shown in scheme 1, the hydrolysis reaction is an example of a sol-gel process and the side product is ethanol. The reaction proceeds via a series of condensation reactions that convert the TEOS molecule into a mineral-like solid via the formation of Si-O-Si linkages. Rates of this ...

sol-gel processIt is shown that the structure of sol-gel-derived thin films depends on the precursor structure and deposition conditions. Weakly branched precursors (reduced D) applied under reaction-limited conditions result in the densest films, whereas branching or aggregation (increased D) ...

condensation. Firstly, methylchlorosilane reacts with water to generate methylhydroxysilane, which then undergoes condensation to form linear or cross-linked PDMS chains. Additionally, PDMS can also be prepared through other methods such as emulsion polymerization, sol-gel process, and thermal ...
