The problem of nanocomposites’ permeability regulation has been attracting the interest of scientists throughout the current decades. The works were dedicated to different models of permeability of the composites containing impermeable layered fillers in polymer matrix. It was shown that polymer films with parallel laid flat impermeable particles of the filler may have the permeability twice or thrice less than the films of the same size, but without a filler. The authors analyzed the influence of nanoparticles on water permeability through nanocomposites obtained on the basis of polymers and flat nanoparticles. The offered correlations take into account the chemical composition of the polymer and nanoparticles, as well as the surface structure in case of chemical modification. The shape of flat particles (tablet, brick, sphere) is also taken into account. The permeability is mostly influenced by nanoparticles concentration, their shape and size orientation angle.
