Since nanocellulose (NC) has excellent strength, modulus, lightness, and thermal stability, it has been widely utilized for composites, electronics, sensors, papers, coatings, films, aerogels, health care, additives, etc. Montmorillonite (MMT) with nano-sized layered structure has a feature of environmentally friendly, readily available in large quantities and cost-effective. Accordingly, MMT, a reinforcing material increase heat resistance and reduce gas permeability, has been incorporated into a polymer matrix to form a nanocomposite. In this study, to attain NC films with enhanced physical properties, we have fabricated a series of NC-based composite films reinforced with MMT nanoclay (0.1-20 wt%) and have characterized their structural features, thermal stability, mechanical performance, and barrier property by using SEM, XRD, TGA, UTM, DMA, and gas permeability tests. |
