Построена математическая модель процесса формирования высокого внутреннего расклинивающего давления в наноструктурах для различных геометрий строения. Исследованы особенности влияния физико-химических факторов на это давления. A mathematical model of the process of forming a high internal wedging pressure in the nanostruc-tures for different geometries of the structure is built. The peculiarities of physicochemical factors influ-ence on this pressure are investigated.

We present the results of molecular dynamics simulations for the capillary imbibition of a drop of an ionic PbI2 melt into inorganic BN, MoS2, and carbon nanotubes. Radial atomic distribution functions are used to characterize the structure of the liquid inside of nanotubes and the kinetics of the penetration. We find that in all cases the PbI2 melt remains liquid but a shell-like structure of the melt along the nanotube axis becomes visible. The filling of MoS2 nanotubes obeys the Lucas−Washburn equation within each shell, whereas the filling of carbon and BN nanotubes follows a modified expression. Both the chemical nature and roughness of the nanotube walls play an important role in the capillary kinetics and the habitus of the embedded liquid.
