Effect of modified clay on the morphological and thermal properties of PLA/PBAT nanocomposites

In this study, new biodegradable polylactic acid /poly butylene adipate-co-terephthalate nanocomposites were developed and prepared using the melt blending method. Sodium montmorillonite clay was modified using organic surfactant, octadecyl ammonium bromide, novel dimethyl dioctadecyl ammonium bromi...
