Natalie A. LaFranzo and Joshua A. Maurer Arsonic Acid Self-Assembled Monolayers Protect Oxide Surfaces from Micronewton Nanomechanical Forces Advanced Functional Materials 23
Hexadecylarsonic acid self-assembled monolayers are prepared on glass, silicon oxide, and titanium oxide via a straight-forward soaking method. These monolayers protect the substrates from micronewton mechanical forces applied in scanning probe microscopy nanoscratching experiments. Compared to hexadecylphosphonic acid, the arsonate shows increased reactivity and greater protection of the substrate from mechanical stress. This system shows excellent potential as a microelectromechanical systems (MEMS) lubricant.
