| Abstract Scope |
The present investigation has been utilized organic compound (OC) and rice husk ashes (SiO2) to modify the performance of the PBAT-PLA blends. It was observed that the addition of both materials increased the tensile strength and elastic modulus of the blend due to the excellent dispersion of the fillers into the blend. The thermal properties of the films indicated an increase in crystallinity and the nucleating effect for both fillers. The SiO2 reduced the thermal stability due to its catalytic effect in matrix decomposition, while OC increased the stability in 6 °C due to the presence of more stable components as fertilizers. The addition of both fillers increased the contact angle. The obtained results classify the materials as good biodegradable films to replace the current LDPE films usually applied for crop protection. At the end of their lifetime, these biodegradable materials can be shattered and buried in the soil. |
