Sustainable Materials with Improved Biodegradability and Toughness from Blends of Poly(Lactic Acid), Pineapple Stem Starch and Modified Natural Rubber

Polymers, Journal Year: 2024, Volume and Issue: 16(2), P. 232 - 232

Published: Jan. 14, 2024

Poly(lactic acid) (PLA), derived from renewable resources, plays a significant role in the global biodegradable plastic market. However, its widespread adoption faces challenges, including high brittleness, hydrophobicity, limited biodegradability, and higher costs compared to traditional petroleum-based plastics. This study addresses these challenges by incorporating thermoplastic pineapple stem starch (TPSS) modified natural rubber (MNR) into PLA blends. TPSS, waste, is employed enhance hydrophilicity, reduce costs. While addition of TPSS (10 40 wt.%) marginally lowered mechanical properties due poor interfacial interaction with PLA, inclusion MNR (1 10 PLA/20TPSS blend significantly improved stretchability impact strength, resulting suitable modulus (1.3 1.7 GPa) strength (32 52 MPa) for diverse applications. The presence 7 wt.% increased 90% neat PLA. ternary exhibited heterogeneous morphology enhanced adhesion, confirmed microfibrils rough texture on fracture surface. Additionally, downward shift PLA’s glass transition temperature (Tg) 5–6 °C indicated compatibility between components. Remarkably, blends demonstrated superior water resistance proper biodegradability binary These findings highlight potential bio-based plastics, such as MNR, contribute sustainable economic models environmental using packaging
