“…(4). Nanofillers such as halloysite nanotubes (HNTs) make it possible, in contrast to other nanofillers, to significantly reduce the ductility loss upon addition in a polymer matrix (e.g., PP, PA6 and linear low density polyethylene (LLDPE) -as reported in ref [106][107][108]). We believe that adding HNT into PA6 blends could be a feasible approach to prepare nanocomposites with a good balance in strength, stiffness and toughness because HNT works well with both PA and polyolefin (e.g., PP, LLDPE).…”

“…HNTs have recently gained considerable attention as a new type of nano-additive for enhancing the mechanical [13][14][15], thermal, crystallization [16,17], and fire performance of thermoplastic polymers, such as polypropylene and polyamide-6 [18], and thermosets, such as epoxy [19]. In recent years, the assembly of ordered metal nanoparticleson one-dimensional nanotubes to synthesize nanocomposites has attracted a great deal of attention in the field of electroanalytical chemistry; particularly in electrochemical sensors [20].…”

The high aspect ratio of nanoscale reinforcements enhances the tensile properties of a pure polymer matrix. Researchers have reported the morphology and tensile properties of thermoplastic polyurethane and halloysite nanotube (TPU-HNTs) nanocomposites, formed through compression moulding processes. Few researchers have reported on TPU-HNTs formed through injection moulding. Therefore, the present work investigates the tensile properties of TPU and HNT nanocomposites via injection moulding. TPU and HNTs were mixed using a brabender mixer with concentrations ranging from 1wt.% to 15wt.% and varying mixing parameters (i.e., mixing speed, mixing time, and mixing temperature). Tensile bars were injection moulded by varying the moulding parameters (i.e., injection temperature, injection time, and injection pressure). A significant increment of tensile strength was found at 1wt.% HNT reinforcement. TPU-HNT nanocomposite with 1wt.% reinforcement exhibited tensile strength of 24.3 MPa, which was higher than that of pure TPU. The Young's modulus of the TPU-15wt.% HNT nanocomposite was 21.5 MPa. Thus, TPU-HNT had improved mechanical properties, compared to pure TPU, due to the addition of a nanofiller.

“…4 The hydrophilicity of both the inner and outer surfaces makes HNTs dispersible in aqueous biopolyelectrolytes such as pectin 14 and chitosan. 20 The combination between polymers and HNTs is a good strategy to develop nanocomposite films with desirable mechanical performance that can be utilized as biocompatible packaging 13,14,21 and as scaffolds for tissue engineering. 16 Filling hydroxypropyl cellulose (HPC) with HNTs was found to cause an increase in the polymer degradation temperature.…”

Selective Functionalization of Halloysite Cavity by Click Reaction: Structured Filler for Enhancing Mechanical Properties of Bionanocomposite Films

Selective modification of the inner surface of halloysite nanotubes (HNTs) by the cycloaddition of azides and alkynes (click reaction) was successfully achieved. Fourier transform infrared spectroscopy and thermogravimetry confirmed that the modification involved only the HNT cavity. Morphological investigations evidenced that the functionalized nanotubes formed microfibers and clusters in the micrometer range. By means of the casting method, these nanomaterials were dispersed into biopolymeric matrixes (chitosan and hydroxypropyl cellulose) with the aim of obtaining nanocomposite films with tunable properties from the physicochemical viewpoint. For comparison purposes, we also characterized composite nanomaterials based on pristine halloysite. The mesoscopic structure of the nanocomposites was correlated with their tensile, thermal, and wettability properties, which were found to be strongly dependent on both the nature of the polymer and the HNT functionalization. The attained knowledge represents a basic point for designing new hybrid nanostructures that are useful in specific purposes such as biocompatible packaging.
