Effect of Fiber and Starch Incorporation in Biodegradation of PLA-TPS-Cotton Composites

Article Preview

Abstract:

Poly (lactic acid) (PLA) is a biodegradable and high-cost polymer which is nevertheless replacing the use of commodities in applications like packaging films, and is widely discarded in the environment. In this work, PLA was homogenized in a K-Mixer with different proportions of thermoplastic starch (TPS), a material with lower cost, and these mixtures were reinforced with natural cotton fibers, seeking to increase the tensile strength without compromising biodegradation. To evaluate the degradation behavior of PLA-TPS-cotton composites, tests were performed to measure the contact angle as well as the effect of hydrolysis and degradation in simulated soil. All the materials showed peak mass retention when removed from the water at 28 days and from the simulated soil at 14 days. The results showed that varying the content of TPS (0, 3 and 5%) caused increased water absorption and rate of degradation, but the fiber content (0, 10 and 20%) can distinguish the influence observed by incorporation of starch. The samples immersed in water presented retention values near those of the PLA matrix itself only for the ratio between fiber and TPS of 2:1 in mass percentage, showing the increased stability of the composite in contact with water.
