Engineers and scientists are faced with a major challenge of developing predictive models of nanoparticles scattering during membrane coating for efficient oil/water separation. Mechanical molecular simulation studies of key parameters or variable for structure/property correlations during nanoparticles coating are analysed on surface energy driven separability in the current study. The tools of stochastic process were used to study the random nature of nanoparticles scattering during membrane coating process using a specific coating technique.
