Improvement in the thermal, mechanical and rheological properties of polyamide-11 (PA11) nanobiocomposite films as a result of the influence of the composition and type of nanofiller

Abstract The structures and properties of different polyamide-11 (PA11) and organically modified Algerian clay nanobiocomposite systems are investigated in this work. The objective of this investigation is to evaluate the potential of modified Algerian clay as a nanofiller by studying of the properties of PA11/Mag-CTA nanobiocomposites with different levels of prepared fillers. Considering the different techniques used, the results show the full potential of the modified Algerian clay, with improvements in both thermal and mechanical properties after incorporation of the nanofiller (Mag-CTA). The intercalated and exfoliated morphology of the developed PA11 nanobiocomposites is demonstrated by the results of the different techniques used. The results indicate that the modified clay has a more significant impact on the thermal, mechanical, and rheological properties of the material than virgin polyamide-11 (PA11) at an equivalent rate of incorporation and low concentration. The optimal loading rate is estimated to be between 3 % and 5 % based on clay mass (Mag-CTA).
