In this research, we develop new numerical scheme of self-consistent field theory (SCFT) to quantify interaction properties between two spherical nanoparticles (NPs) coated with end-grafted homopolymers in chemically identical polymer melts. In our numerical SCFT calculation, two-dimensional finite volume method (FVM) which efficiently conserves the amount of material in curvilinear coordinate is adopted, and the differential equation for partition function is solved in real space with Multicoordinate-system (MCS) scheme which makes use of the mirror symmetry between the two particles. The stabilization mechanism for dispersion is investigated by calculating interaction potential between two polymer-coated NPs as functions of grafting density, relative chain size and distance between the two particles. Our results reveal that self-assembly can be induced by the short distance repulsion between particles. |
