Abstract:

This article aims to revisit the research of surface wetting on self-assembled monolayers(SAMs) of organic molecules. It starts with a brief overview of the growth mechanism governing the self-assembly of organic molecules, followed by discussion of temperature-induced phase transition of SAMs. In the following sections, the surface wettability of SAMs is discussed in three main aspects on the basis of a collection of studies reported in a time span of 100 years, including (1) the contribution of terminal methyl groups to total surface energy of SAMs; (2) manifestation of the interactions between terminal polar groups and their interactions with water in SAM surface wettability, and the newly-discovered effect of molecular-level roughness of SAMs on their surface wettability. These studies will be put in new prospective in order to shift conventional thermodynamic description of surface wetting phenomena to new molecular-level interpretation and design of surface wettability.
