Abstract
   Cellulose Nano fibrils have strong reinforcing properties when incorporated in a compatible polymer matrix. The aim of this study was to investigate the thermal and mechanical properties of the nanocomposite Nano composite made of poly vinyl alcohol (PVA)- Nano fiber celluloses (NFC)-Nano silicon dioxide Samples of the nanocomposite Nano composite were prepared by the casting method with different Nano cellulose and Nano silicon dioxide loadings. Then, samples were exposed to tensile test, Thermo Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The morphology of both neat poly (vinyl alcohol) and Nano composites was explored by using the field emission Scanning Electron Microscope technique (SEM). Results of tensile test indicated that the tensile strength and Young’s modulus of poly (vinyl alcohol) composite Nano composite were significantly improved with the increase of cellulose Nano fibrils loading. Also, the Ultimate strength (UTS) decreased as the Sio2 contents increased. The addition of 5 and 10 wt% of Nano silicon dioxide successfully improved the thermal stability and crystallinity of the PVA/Nano cellulose composites. Results indicated that the Nano cellulose had a great potential to reinforce PVA polymers.
