1 | 2020 thesis | Thermomechanical, thermal properties and structural morphology of poly (lactic acid) reinforced with titanium oxide nanofiller Mohammed Zorah Hassan The aim of this study was to investigate the thermomechanical, thermal properties and structural morphology of modified poly (lactic acid) (PLA) reinforced with titanium oxide (TiO2) nanofiller. The PLA composites were prepared by solvent casting followed by hot press method using tributyl citrate (TBC) as a plasticizer and TiO2 nanofiller for reinforcement. The thermomechanical, thermal behavior and structural morphology of PLA composites were characterized using dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), thermo-gravimetric analysis (TGA) and field emission scanning electron microscopy (FESEM). The crystallinity and transparency of the composites were studied using X-ray diffraction analysis and UV-Vis transmittance spectroscopy. Results showed TBC acts as a successful plasticizer that increased flexibility of the composite with improved crystallinity from 17.52 % to 38.56 % at the optimum loading of 7.0 w/w % TBC.
