Production of Eco-Sustainable Materials: Compatibilizing Action in Poly (Lactic Acid)/High-Density Biopolyethylene Bioblends

Motivated by environment preservation, the increased use of eco-friendly materials such as biodegradable polymers and biopolymers has raised interest researchers polymer industry. In this approach, work aimed to produce bioblends using poly (lactic acid) (PLA) high-density biopolyethylene (BioPE); due low compatibility between these polymers, evaluated additional influence compatibilizing agents: (ethylene octene) ethylene elastomer grafted with glycidyl methacrylate (POE-g-GMA EE-g-GMA, respectively), polyethylene maleic anhydride (PE-g-MA), acrylic acid (PE-g-AA) block copolymer styrene (ethylene-butylene)-styrene (SEBS-g-MA) thermal, mechanical, thermomechanical, wettability morphological properties PLA/BioPE. Upon agents’ addition, there was an increase in degree crystallinity observed DSC (2.3–7.6% related PLA), thermal stability verified TG (6–15 °C for TD10%, 6–11 TD50% 112–121 TD99.9% compared PLA) mechanical elongation at break (with more expressive values addition POE-g-GMA SEBS-g-MA, 9 10%, tensile strength (6–19% PLA/BioPE bioblend) a significant impact strength, evidence plastic deformation through SEM, promoted PLA/ BioPE phases improvement. Based on gathered data, added compatibilizers provided higher performing The compatibilizer considered provide best relation bioblend, well PLA matrix, mainly approximately 133 100% respectively. Therefore, new ecological can be manufactured, aiming benefits society, contributing sustainable development stimulating consumption eco-products.
