บทคัดย่อ

The objective of this work was to improve mechanical properties, thermal resistance, and biodegradability of poly(vinyl chloride) (PVC) by the addition of poly(lactic acid) (PLA), poly(butylene adipate-co-terephthalate) (PBAT), and wood flour (WF). The samples made from a mixture of PVC/PBAT exhibited the highest impact and tensile properties, while properties of the samples made from PVC/PLA had the highest flexural and thermal properties, PVC/PLA/PBAT mixed samples exhibited average mechanical properties. The addition of WF to all the blends increased impact strength, flexural properties, Youngâ€™s modulus, thermal resistance, and biodegradability of the samples in comparison to those of the neat PVC and its blends. Composite samples of PVC/PBAT/WF showed the highest impact strength, while PVC/PLA/WF composite had the highest flexural and thermal resistance. The samples manufactured from a mixture of PVC/PLA/PBAT/WF had the highest tensile strength and Youngâ€™s modulus. The overall results in this work suggested that the enhanced properties of PVC samples were strongly influenced by the compatibility between polymer blend matrix and WF particles.
