Biodegradable polymers are attracting attention as one of the solutions for the problem of increasing plastic waste. Although biodegradable polymers are not the only solution for plastic pollution they can provide a sustainable solution, especially in applications where it is not easy to collect the polymers back after use. The ester functional groups in polymer backbone repeat units can be hydrolyzed under appropriate environments leading to the break of the polymer chain. The trade-off between the degradability and physical properties of polymers. To overcome this problem we made film through solution blending of amorphous poly(D, L-lactide) and semi-crystalline poly(L, L-lactide) (PLLA) with an aim to achieve a good balance of mechanical properties and degradability. In this study, a composite of magnesium oxide whiskers (MgO)/PLLA/PDLLA was prepared through solution casting. The properties of the composites with different MgO contents were investigated in terms of crystallization, mechanical properties, water absorption, and biodegradability. |
