Abstract
It is found that the critical temperature in the formation of self-assembled n-hexadecyltrichlorosilane (HTS) monolayers on mica depends on the water content in the solvent dodecane. Under the condition of 35±2 ppm water content in dodecane, the critical temperature is found at 31±1 °C. When the water content in dodecane is lowered down to 13±2ppm, no critical temperature is found in the temperature range of 10-55 °C. Our results indicate that the critical temperature is subject to the extent of hydrolysis of HTS molecules in bulk phase of solution. A reaction mechanism of monolayer formation is discussed. © 2001 Elsevier Science B.V.
