Mechanical properties of halloysite nanotubes (HNTs) filled polyamide 11 (PA 11) nanocomposites

This study focused on the influence of different filler loading on mechanical properties of bio-based polyamide 11 (PA 11) and Halloysite nanotubes (HNTs) nanocomposites. Nanocomposites of 100 phr of PA 11 with 2, 4 and 6 phr of HNTs were compounded using the Brabender twin-screw extruder and injected the materials into the injection molding machine processes. Tensile, flexural and impact testing will be observed a homogenous dispersion of HNTs in PA 11 matrix. Incorporating of PA 11/HNTs will improve the stiffness and interfacial adhesion between the matrix and filler. The results show the effectiveness of HNTs on the mechanical properties of the PA 11 matrix. Thus, PA 11 can become a custom-made material with multifunctional characteristics with the addition of nanofillers.
