“…The laminate film reduced permeability to CO 2 by more than one order of magnitude and reduced H 2 S permeability to an undetectable level. Cherif et al [167] studied the diffusion behavior of Irganox ® 1076 antioxidant (BASF, Ludwigshafen, Germany) in a novel food contact packaging film consisting of high-density polyethylene (HDPE)/cloisite ® 15A (BYK Additives & Instrument, Wesel, Germany) nanoclay composites. The diffusion coefficients were determined according to Fick's law, which showed that the maximum diffusion rate reduction of the antioxidant reached 78% with a three wt% nanoclay loading.…”

Recent advancements in material technologies have promoted the development of various preparation strategies and applications of novel polymer–nanoclay composites. Innovative synthesis pathways have resulted in novel polymer–nanoclay composites with improved properties, which have been successfully incorporated in diverse fields such as aerospace, automobile, construction, petroleum, biomedical and wastewater treatment. These composites are recognized as promising advanced materials due to their superior properties, such as enhanced density, strength, relatively large surface areas, high elastic modulus, flame retardancy, and thermomechanical/optoelectronic/magnetic properties. The primary focus of this review is to deliver an up-to-date overview of polymer–nanoclay composites along with their synthesis routes and applications. The discussion highlights potential future directions for this emerging field of research.

“…Ait cherif et al 45 also found activation energies of 103.12 and 117.05 kJ mol −1 for D p in the HDPE and HDPE/C15A, respectively, thus confirming that the incorporation of nanofillers slow down the diffusion of molecular additives.…”

“…All these results are consistent with the expected improvements and the literature data. As an example, the diffusion of Irganox 1076 in HDPE/C15A was studied by Ait cherif et al 45 using FTIR spectroscopy. Values of D p of 9.0 × 10 −11 and 7.8 × 10 −10 cm 2 s −1 were obtained at 80 and 100°C, respectively, for HDPE filled with 3 wt% of nanoclays.…”

Knowing the diffusion coefficients of antioxidants in packaging materials is essential to assess their effectiveness in protecting materials against oxidation, but also to prevent their eventual migration to food. In this work, the diffusion of a commercial phenolic antioxidant (Irganox 1035) was measured experimentally in pristine high‐density polyethylene (HDPE) and in HDPE nanocomposite filled with 3 wt% of nanoclays (Cloisite® 15A). Diffusion experiments were performed using the Roe's method between 60 and 100°C. The local concentration of Irganox1035 in each film was measured by UV–Vis spectroscopy from the UV absorbance at 282 nm. The adjustment of the experimental data by Fick's second law allowed us to deduce the values of the diffusion coefficient of Irganox1035 at each temperature and to show that the temperature dependence of this coefficient obeys an Arrhenius' law. It is shown that the incorporation of 3 wt% of Cloisite®15A into HDPE significantly hinders the diffusion of Irganox 1035 and increases its activation energy. Several mechanistic assumptions could explain this result, first the increase in the tortuosity of diffusion paths, but also the possible establishment of strong intermolecular interactions between the antioxidant and some chemical groups on the nanofiller surface, or even the formation of an interphase with reduced molecular mobility around the nanofillers.

“…TEM and XRD investigations on PLA/EVA blend nanocomposites were carried out to reveal the clay dispersion, exfoliation/intercalation states and its partition in the blend phases, as main controlling factors, which affect gas barrier properties of the final system. [38] The TEM micrographs of PLA/EVA (75/25) blend nanocomposites in the presence and absence of compatibilizer are depicted in Figure 4a,b. Combination of mainly intercalated and some exfoliated structures are seen in both the systems confirmed by XRD analysis too (Figure 4c).…”

Poly (lactic acid) (PLA)‐based compounds are widely used in thin‐film and food packaging industries. Herein, PLA/ethylene vinyl acetate copolymer (EVA)/nanoclay nanocomposites are prepared in various compositions by melt blending. The gas permeability against N2, CO2, and O2 gases is determined as a function of composition and morphology of the nanocomposites. Inclusion of high aspect ratio of platelet‐like nanoclay to the blend reduces the gas diffusion. The best barrier properties against all gases is observed on introducing 5 wt% poly(ethylene/n‐butyl acrylate glycidyl methacrylate) copolymer as compatibilizer to the PLA/EVA/nanoclay (75/25/5) system. The scanning and transmission electron microscopic analyses and wide‐angle X‐ray scattering studies reveal that inclusion of compatibilizer to the filled‐blends improves the blend morphology, dispersion state, and intercalation level of clay platelets which are preferably localized at the interface of the blend. Analysis of selectivity parameter (α) shows the lowest O2 permeability and the highest αCO2/N2 and αO2/N2 values for the compatibilized filled‐blend (75/25/5/5). In situ aspect ratio of clay and the degree of intercalation are theoretically evaluated based on the permeability data using various empirical models. It is found that the compatibilized filled‐blend has the highest aspect ratio and intercalation level that are responsible for the optimum perm‐selectivity performance.
