On the transition from partial wetting to complete wetting of methanol on graphite

Abstract

Excellent agreement with experiment for methanol adsorption on graphitized carbon black at low temperatures by Monte Carlo simulation. Incomplete wetting and complete wetting are observed at a range of temperatures above the triple point.

Molecular Insights into the Effect of Temperature and Functional Groups on the Nonwetting, Prewetting, Partial Wetting, and Complete Wetting Transitions of Ethanol on Graphite

“…Similarly, partial wetting (or incomplete wetting) was recently explored by studying methanol adsorption on Carbopack F over a triple-point temperature ( T tr ) range using GCMC. Partial wetting occurred at temperatures between complete wetting and nonwetting since most of the H and O atoms of methanol on the second layer pointed downward to form H bonds with methanol molecules concentrated on the monolayer. − , At a temperature above the triple point of methanol, the isotherm showed partial wetting transition and revealed, since the monolayer was partly filled, some 3D structures . It would be interesting to note how the behavior of fluids in the same category as methanol and ethanol would be.…”
