Abstract
The influence of chemical and physical parameters of polymer nanocomposites on the water permeability is analyzed. The chemical structure of the matrix polymer and the polar groups grafted onto the surface of the nanoparticles lead to the greatest influence. A large influence is exerted by the concentration of nanoparticles, their shape and size distribution. The direction of the penetration front in the nanocomposite sample has a lesser effect.</jats:p
