Preparation and Micro-Tribological Study on Dually Mixed Self-Assembled Monolayers

A series of dually mixed self-assembled monolayers were prepared by a simple step-by-step method.Four carbonyl chlorides with different chain lengths were selected and assembled onto a N-[3-(trimethoxylsilyl)propyl] ethylene diamine self-assembled monolayer.Different mixed films were obtained by controlling the ratio of co-deposited carbonyl chlorides.The structures of the films were characterized by measuring their contact angles,ellipsometric thickness,and atomic force microscopy.No phase separation was observed in the mixed films.Micro-tribological studies were also carried out on the films.It was found that frictional coefficients decreased as the ratio of the longer component was increased.
