Resumo: | Studies using starch to produce biodegradable materials have proved attractive due to its availability and low cost in relation to commercial biodegradable polymers, such as poly (lactic acid) and others. Starch-based materials do not have adequate mechanical properties for production and use on a commercial scale, requiring mixtures (blends) with other biodegradable polymers to improve these properties. However, these blends need compatibilizers due to the immiscibility between the starch and the polymer. The present work aimed to study the effect of different compatibilizers (3-(trimethoxysilyl) propyl methacrylate, citric acid, and maleic anhydride) on the functional properties of biodegradable starch and poly (lactic acid) (PLA) materials produced by extrusion and thermoplastic injection. Citric acid was considered the best compatibilizer for these materials because it improved the processability, and the materials presented properties suitable for applications where good mechanical resistance is required. In addition, the materials containing citric acid and maleic anhydride were more uniform from the morphological point of view. |

Os materiais à base de amido não apresentam propriedades mecânicas adequadas para produção e uso em escala comercial, necessitando de misturas (blendas) com outros polímeros biodegradáveis para melhorar essas propriedades. No entanto, essas blendas necessitam de compatibilizantes devido à imiscibilidade entre o amido e o polímero. O presente trabalho teve como objetivo estudar o efeito de diferentes compatibilizantes (3- metacriloxipropiltrimetoxisilano, ácido cítrico e anidrido maleico) sobre as propriedades funcionais de materiais biodegradáveis de amido e poli (ácido lático) (PLA) produzidos por extrusão e injeção termoplástica. O ácido cítrico foi considerado o melhor compatibilizante para esses materiais, pois melhorou a processabilidade, e os materiais apresentaram propriedades adequadas para aplicações onde se exige boa resistência mecânica. Além disso, os materiais contendo ácido cítrico e anidrido maleico foram mais uniformes do ponto de vista morfológico.Los estudios que utilizan amida para la producción de materiales biodegradables también han demostrado su atractivo debido a su disponibilidad y bajo costo en comparación con los polímeros biodegradables comerciales como el poli(ácido láctico) y otros.

Estas mezclas necesitan compatibilizadores debido a la inmiscibilidad entre la amida y el polímero. El objetivo de este trabajo es estudiar el efecto de diferentes compatibilizantes (metacrilato de 3-(trimetoxisilil)propilo, ácido cítrico y anhídrido maleico) sobre las propiedades funcionales del almidón y poli(ácido láctico) (PLA) materiales biodegradables producidos por extrusión e inyección de termoplásticos. .
