چکیده انگلیسی
The nanocomposite films were prepared using Eucommia ulmoides gum (EUG) matrix reinforced with nanocrystalline cellulose (NCC) at different concentrations. Subsequently, the obtained films were characterized by Raman spectra, AFM, XRD, TGA, and DSC. Meanwhile, the wettability, mechanical, and water vapor barrier properties of these films were analyzed. AFM noticed that the average sizes of NCC were 81.95Â ÃÂ 50.17Â ÃÂ 13.06Â nm, while the size of molecular chain for EUG was 2530Â ÃÂ 57.33Â ÃÂ 1.28Â nm. In comparison with control film, a certain amount of NCC obviously improved elongation at break and enhanced their crystallinity and ÎHm. More importantly, NCC/EUG nanocomposite films presented lower thermal stability, glass transition temperature (Tg), melting temperature (Tm), and water vapor permeability (WVP) values, especially the WVP values of 4% NCC film were the lowest as 0.28Â ÃÂ 10â9, 0.30Â ÃÂ 10â9, and 0.58Â ÃÂ 10â9Â g/m/h/Pa at RH 34%, 55%, and 76%, respectively.
