Valorization of starch nanoparticles on microstructural and physical properties of PLA ‐starch nanocomposites

International audienceStarch nanoparticles, synthesized from native starch through the hydrolysis approach, are considered as potential reinforcers to sustainable biodegradable nanocomposite with poly(lactic)acid. Some properties of nanocomposites are upgraded to expand their applications compared to poly(lactic) acid. As relevant, starch nanoparticles are spherically shaped with mainly distributive sizes under 80 nm. Especially, they are homogeneously dispersed in the matrix polymer at high content, resulting in improving the interfaces between matrix polymer and starch nanoparticles, thermal stability, and mechanical properties of nanocomposites
