“…The concentration gradient is determined by the solubility of the diffusion inside the polymer molecules and the lateral dimension of film barrier 14 .It should be noted, the presence of Graphene Oxide will evidence the nucleation sites, altering the polymer morphology crystallization. The formation of smaller crystallites tends to increase the modulus of elasticity, but the impact creep resistance characteristics of the material are also altered stems and affects the morphology of the nanocomposite.…”

This paper shows a study of Nanocomposite formed by adding reduced Graphene oxide with high acidity and polystyrene. The interest and research in the material is due to the ability of these nanoparticles significantly altering the electrical and mechanical properties of the polymer, even addition of small levels. The existence of functional groups on the graphene oxide containing abundant oxygen such as; epoxy, hydroxyl and carboxylic acid, can be well dispersed in the polymer because of its good interaction with polymer chains. In this study we used the solution by dispersing method to that made the use of solvent tetrahydrofuran (THF), for purposes of obtaining a reaction with functionalization of graphene oxide / polystyrene in time of 48 hours. The analyses of physical-chemical characterizations were made diffraction X-ray (XRD), scanning electron microscopy (SEM), Infrared Spectroscopy (IRD), Thermogravimetric Analysis (TG) and Differential calorimeter by scanning (DSC). The results obtained by XRD diffraction pattern showed a strong expansion in the peak, indicating amorphization on single sheets of graphene oxide due to distorted sp 3 sites CO. The morphology of the nanocomposite structure was with surface roughness, folds and rough predominant oxidation process of oxygenated functional groups. Their techniques showed the range of absorption, crystallinity degree and the mass loss. Finally, current and future possible applications of formed polystyrene nanocomposite/ graphene oxide show high acidity efficiency in the use of thin films.

“…Failure time of 8wt% doped barrier film was almost doubled than that of the undoped, extending from 9 days to more than 20 days, and the WVTR decreased to 1.6×10 -4 g/m 2 /day, indicating the presence of the clay sheet indeed improved mouisture barrier of the multi-film. The improved performance of the barrier film is attributed to impermeable clay nanosheets create complicate laminated structure which extends the moisture permeation path [5][6].…”

Organic electronic devices, such as organic light‐emitting diodes (OLEDs), are very sensitive to air environment, so it is necessary to encapsulate these devices to increase the service life[1−2]. In this study, we report a high transparent inorganic /organic multilayer barrier film, in which the inorganic layer is a high‐quality SiNx layer and the organic layer is clay nanoparticle‐embedded organic—inorganic hybrid (C—H) nanocomposite.
