Alkylthiolate monolayers have been extensively studied as wear inhibitors for metal surfaces. Recently, it has been shown that dithiocarbamates form quite robust monolayers on the surface of several metals. Two model compounds, sodium dioctadecyldithiocarbamate and sodium 2-(perfluorodecyl) diethyldithiocarbamate were synthesized from the corresponding amines and carbon disulfide. Monolayers of the dithiocarbamates were deposited on glass using the Langmuir-Blodgett technique. Monolayers were deposited at several temperatures and surface pressures. The coefficient of friction and water-substrate contact angle of the monolayer-coated slides were measured.
