“…HNTs used in this study have an average diameter of 80 nm, a length of about 1.2 l, and a density of 2.5 g/cm 3 (Natural Nano, USA). Polyamide-11 (PA-11) is an injection grade (BMNO TLD, RilsanV R , Arkema).…”

“…Polyamide matrices are often used to develop such nanocomposites. In particular, the literature extensively reported the numerous efforts produced to improve the thermomechanical, rheological, barrier, and flame retardancy properties of polyamide-66 by incorporating a small amount of nanofillers such as montmorillonite (MMT), [3][4][5][6] inorganic particles, 7,8 and carbon nanotubes (CNTs) [9][10][11] to produce highperformance polymeric nanocomposite materials.…”

Bio-based polyamide 11 and natural halloysite nanotubes (HNTs) were used for the preparation of PA-11/HNT nanocomposites with varying nanotubes concentrations by melt extrusion using a masterbatch dilution process. The prepared nanocomposites were analyzed for microstructural changes, transparency, thermal stability, rheological behavior, dielectric, and mechanical properties. The HNT nanotubes are well dispersed in PA-11 matrix in the studied composition range as shown by microscopy and spectrophotometry. Interestingly, good halloysite dispersion in PA-11 matrix increases the tensile strength and Young modulus of PA-11 without sacrificing the ductility. Highly dispersed nanotubes also bring favorable changes in the thermal stability, dielectric, and rheological characteristics of PA-11. Additionally, glass transition temperature, crystallization temperature, and degree of crystallinity of the nanocomposites tend to increase with increase in nanotubes loading. Thus, PA-11 can become a tailor-made material with multifunctional characteristics, thanks to the addition of HNTs.

“…The standard methods for the characterization of organoclay and their nanocomposites are X-ray diffraction, FTIR, and elemental and TGA. XRD gives information about the gallery structure of the silicate in the nanocomposite and the amount of non-exfoliated, ordered stacks of clay (Naveau et al, 2011). For this research, the XRD patterns of the nanocomposite LLDPE/OMMT containing 1-5 wt% organoclay were compared.…”

“…The ion exchange between the organic surfactant and sodium ions in the interlayer of MMT expands the interlayer space, allowing large polymer molecules to enter. This process improves the miscibility of MMT with organic polymers, thereby achieving a good dispersion of MMT in the polymer matrix (Naveau et al, 2011;Zhao et al, 2010).…”

Low linear density polyethylene/organo-montmorillonite (LLDPE/OMMT) nanocomposites at 1-5 wt% OMMT loading were prepared by the melt intercalation technique. The OMMT was synthesized via an ion exchange reaction by replacing the interlayer of sodium ions (Na + ) in the repeating unit of silicate layers of montmorillonite (MMT) with the cationic surfactant in the form of trihexyltetradecylphosphonium (THTDP) ions. The obtained OMMT and its nanocomposites were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and elemental and thermogravimetric analyses. The interlayer spacing of MMT expanded from 1.41 to 2.29 nm due to the accommodation of THTDP ions in the intergallery of OMMT. The introduction of THTDP in the interlayer of OMMT rendered better dispersion of OMMT layers in the LLDPE/OMMT nanocomposites and significantly improved the thermal degradation properties of nanocomposites as compared to the pristine LLDPE.
