Composite Nanoarchitectonics of Poly(lactic acid)/Metal Organic Framework with Property Investigations Toward Packaging Applications

Résumé

In this study, poly(lactic acid) (PLA), metal organic framework (MOF-5) and metal organic framework/graphene oxide (MOF-5/GO) were associated to prepare nanocomposites through melt extrusion method using a vertical co-rotating twin-screw micro compounder. GO, MOF-5 and MOF-5/GO composites were synthesized, respectively, using the modified Hummer's method, facile method at room temperature and in situ incorporation of GO into MOF-5 precursors. PLA and MOF nanocomposites were obtained with the incorporation of 3 and 5% w/w of MOF-5 and MOF-5/GO nanofillers into the PLA matrix. The morphological, rheological, thermal, impact tests and barrier properties of the composites were evaluated by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), impact resistance tests and water vapor permeability test (WVP). According to the XRD results, MOF-5 and MOF-5/GO composites were successfully incorporated into the PLA matrix without altering the crystal structure of the MOF-5 and MOF-5/GO composites. The SEM images and FT-IR spectra indicate that MOF-5 and MOF-5/GO fillers are compatibles with PLA matrix. In the rheological study, the non-terminal behavior observed for PLA nanocomposites indicates pseudo-solid behavior, characteristic of a good dispersion state of the used nanofillers. The decrease in cold crystallization enthalpy indicates a high potential of these materials in various applications including gas separation, energy and packaging. Water vapor permeations (WVP) were strongly reduced by the incorporation of MOF-5/GO, and the better results are obtained with PLA/MOF-5/GO containing 5 mass% of MOF-5/GO-5. The results indicate that the structure-properties relationship is established and packaging application can be considered for these materials.
