“…Another factor which may also have influenced OTS self-assembly on the reduced atmosphere, 70°C samples was the large delay between cleavage of the mica and OTS modification. Bierbaum and Grunze demonstrate that different preparation environments affect the OTS assembly process on silicon (25). The role of surface water as a "lubricating" layer on which OTS molecules diffuse is evident in comparing the hydrated surfaces with the partially dehydrated surfaces in Fig.…”

“…The continued existence of many small clusters among these larger islands supports a heterogeneous island nucleation theory. Bierbaum and Grunze report a similar distribution of OTS clusters and islands on silicon substrates (25). It is not known why cluster aggregation occurs more readily at certain sites on the mica surface, this may be a result of an uneven distribution of water on the surface during silanization or other local changes of the mica surfaces such as counterion density.…”

“…Both island (24,25) and uniform growth mechanisms (4, 6) have been reported for OTS assembly on silica substrates; thus the properties of the substrate alone do not dictate which model prevails. Parameters such as silanization temperature and hydration greatly influence monolayer self-assembly (26)(27)(28)(29)(30)(31).…”

Partial monolayers of octadecyltrichlorosilane (OTS) were formed on mica under different reaction conditions in which the silanization temperature, time, and amount of water adsorbed on the mica substrates were varied. OTS surface coverage increased with silanization time for all samples; however, the amount and distribution of adsorbed OTS varied greatly under these different reaction conditions. AFM analysis showed that OTS formed two phases on mica silanized at 25°C: condensed "island-like" domains and expanded "liquid-like" domains. Partially dehydrated mica silanized at 9°C, however, displayed only condensed domains which were of smaller size compared to those on the 25°C samples. The lateral diffusion and aggregation of small condensed OTS domains to form larger aggregates was evident on all surfaces except the 25°C partially dehydrated mica. A uniform distribution of many small condensed domains surrounded by expanded OTS phases was seen instead. Extended annealing resulted in surface diffusion and aggregation of these domains and nucleation of new condensed domains from the surrounding expanded OTS phases. These observations are consistent with a deposition, diffusion, and aggregation model (DDA) which allows for activated diffusion; however, rigorous modeling is not presented here.

“…Self-assembled monolayers (SAMs) have received a great deal of attention for their fascinating potential technical applications such as nonlinear optics and device patterning (Horne & Blanchard, 1998;Morhard et al, 1997;Bierbaum et al, 1995). They also have been used as an ideal model to investigate the effects of intermolecular interactions in the molecular assembly systems (Schertel et al, 1995;Yan et al, 2000;Himmel et al, 1997;Jung et al, 1998).…”

Challenges and developments of self-assembled monolayers and polymer brushes as a green lubrication solution for tribological applications

et al. 2015

ab Self-assembled monolayers (SAMs), after originally being investigated due to their functions in changing surface wettability, have been significantly developed over the years. Many types of SAMs have been developed on a variety of substrates. However their formation mechanism, rate and quality are found to be influenced by many factors. A range of SAMs including single-and multi-component are included in this review with focus on the nano and macro tribological properties. More recently, surface initiated polymer brushes, i.e. macromolecular assemblies attached to a substrate, have emerged to be an alternative and promising method for surface modification. The ability to tether these macromolecules to tribological contacts is key to their resistance to shear under loaded contacts. This review also covers atom transfer radical polymerisation (ATRP) and the role of this technique in developing new lubrication solutions. Particular care has been taken to include the development of lubrication solutions for silicon nitride due to the importance of this material as an engineering ceramic. This paper reviews the stateof-the-art development of SAMs and polymer brushes especially the potential opportunities and challenges in applying them in tribological contacts as a lubrication solution.
