The structure and surface pressure of compressed monolayers consisting of silica nanoparticles at the water-air interface have been studied by means of molecular dynamics computer simulations. The simple "hexagonal array of monodisperse particles" model overestimates the range of the repulsive interparticle potentials between the nanoparticles in a monolayer. On the basis of the results of the simulation we proposed a method to assess the error of the estimation. We also investigated the relevance of the rate of compression in terms of the structure formation and the simulated surface pressure-area isotherms, and considered a possible collapse mechanism based on the different potential energies of the ejected particles.
