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.

Today great attention is paid to production and research of the mechanical and termal properties of nanocomposites based on polyimides. These polymers are heatresisting and possess the increased mechanical properties in wide range of temperatures. Various nanoparticles are introduced into polyimides: graphite nanotubes and flatparticles, the particles of SiO , the surface of which is modified, the particles of ZrOandmontmorillonite, etc.The authors analyzed the influence of nanoparticles on the glass transition temper-ature T and elastic modulus E of the polyimides based on 1,3-bis-(3,3’,4,4’-dicarboxy-phenoxy)benzene and 4,4’-bis-(4-aminophenoxy)biphenyl, and pyromellitic dianhydride and oxydianiline. Nanoparticles introduced in small amounts are produced of graphite and ZrO . The suggested ratios take into account the chemical structure of the polymer and nanoparticles, as well as the structure of their surface in case of chemical modification; the concentration of nanoparticles and their form, the number of polar groups on the surface. The number of polar groups and nanoparticles’ concentration have the greatest influence on T . The elastic modulus of nanocomposites depending on nanoparticles’ concentration is connected with van der Waals volume of the repeating unit of polymer and nanoparticle.
