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

Starch 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.

Automated summary

Starch nanoparticles synthesized from native starch through the hydrolysis approach are considered potential reinforcers for sustainable biodegradable nanocomposites with poly(lactic)acid. These nanoparticles, which are mainly spherical in shape and distributed in sizes under 80 nm, are able to improve the interfaces between matrix polymer and starch nanoparticles, as well as enhance the thermal stability and mechanical properties of nanocomposites when homogeneously dispersed in the matrix polymer at high content.
