Abstract
The computer simulation of the processes of the nucleation and growth of nanoparticles in heterogeneous media (for example, in polymer solution or porous polymer matrix) in the presence of surfactant has been carried out. Heterogeneous medium has been modeled by a system of pores that limit the region of the nanoparticle formation. It is assumed that surfactant molecules, which were present in the system initially, adsorb on the surface of the nanoparticles and slow down their growth in the oversaturated solution. The complete blocking of the nanoparticles occurs when their surface is covered by the surfactant molecules to a certain degree and their growth stops. It is shown that the degree of heterogeneity and the value of surfactant concentration significantly affect both the mean size of the nanoparticles and the character of their size distribution.
