Web7 Oct 2024 · Studies using CTAB–silane micelles have shown that control of their assembly can be achieved in three ways: first, tetramethyl orthosilicate (TMOS) is used because it has a higher hydrolysis rate... Webc) Effect of temperature The system temperature increases, the CMC initially decreases and then slightly increases, as shown in Figure (6). Owing to the smaller probability of hydrogen bond formation at higher temperatures, the initial decrease of the CMC with temperature is a consequence of the decreased hydrophilicity of the surfactant molecules.
