Abstract
An off-lattice Monte Carlo simulation using a simplified bead-spring polymer model has been applied to analyzing spreading of ultra-thin lubricants over molecularly smooth solid surfaces. Reptation Model, Rouse Model and the two methods of initializing lubricant films were examined to determine appropriate models for lubricant molecules. It is concluded that Rouse Model and the initialization method that simulates the dip-coating method are essential for the simulation. The results are in good accordance with experimental results. Diffusion coefficients of lubricant films are eventually obtained through the profiles of lubricant films.
