Organic Materials in Nanochemistry

Many revisions have demonstrated developments in permeability reduction to gases, moisture and organic vapors resulting from the accumulation of low concentrations of layered some nanoparticles to numerous thermoplastic matrices. This is mostly due to their nanometer scale element size and intraparticle spaces. The desired properties are typically reached at low filler volume portion, allowing the nanocomposites to retain macroscopic dispersion and low thickness of the polymer. The geometrical outline of the particle plays an important role in determining the properties of the complexes. The improved nanocomposite barrier performance illustrated by many samples has been explained by the tortuous track model, in which the existence of impermeable some platelets produces an overlapped construction that hinders penetrate diffusion and thus reduces the permeability of the material
