Bacterial Cellulose Nanocrystals from Low Cost Resources Reinforced Poly(ethylene oxide) Nanocomposites
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
This study investigated the effect of bacterial cellulose nanocrystals (BCNCs) derived from low cost resources as reinforcing nanofiller in poly(ethylene oxide) (PEO) based nanocomposites. The nanocrystals isolated from bacterial cellulose produced from the pineapple peel waste juice as a culture medium. TEM images showed that the morphology of BCNCs has a needle-like structure with an average length and diameter of 325 and 25 nm, respectively. The crystallinity index of BCNCs determined by XRD was 88%. The PEO/BCNCs nanocomposites were prepared by mixing the aqueous solution of PEO with the BCNCs suspension. The solid films were obtained by solution casting method. The morphology of nanocomposite films was characterized by SEM. The thermal and mechanical properties of nanocomposite films were characterized by DSC and tensile test, respectively. The incorporation of BCNCs into the PEO matrix change the morphology of both crosssection and surface films to be more regular and this lead the increasing in crystallinity and mechanical properties. However, the thermal properties of PEO matrix were decreased.
