ABSTRACT:
Molecular Dynamic simulations have been carried out to investigate the dynamics of monododecyl diethylene glycol (C12E2) surfactant monolayer adsorbed at the air/water interface. The simulation was carried out by taking C12E2 monolayer at a surface coverage to that at its critical micelle concentration (34 Å2/molecule). It was observed that both the head and tail parts of the surfactant chains are significantly tilted away from the normal to the interface. It is clear that the headgroups are more tilted toward the plane of the interface compare to the tails. It is also observed that head part of the surfactant shows faster reorientational dynamics in compare to tail part of the surfactant.
