Model of absorption of gaseous naphthalene by ordered layers of polymer submicroparticles with nanostructured shells

Grushnikova, E.; Lebedev-Stepanov, P.; Koshkin, A.; Menshikova, A.; Mitrokhin, V.; Molchanov, S.; Alfimov, M.

2012 Nanotechnologies in Russia

doi:10.1134/S1995078012060043

A new model describing the kinetics of absorption of naphthalene vapor from the atmosphere in three-ordered layers of polymer submicroparticles (400–450 nm) with both simple and porous (modified) shells and an impenetrable core was proposed. The experiment examined the layers of polymer particles...
