polymeric nanocomposites with improved mechanical, flame retardant, and electromagnetic shielding properties by various approaches has been developed. [15-20] Yu et al. [17] modified the exfoliated Ti3C2 in aqueous solution by using two kinds of cationic modifiers, i.e., cetyltrimethyl ammonium bromide and tetrabutyl phosphine chloride, and studied fire safety properties and flame-retardant mechanism of MXene/TPU nanocomposites. Thermoplastic polyurethane (TPU) is one of the most commonly used elastomers, and it is a multisegmented copoly mer composed of hard segments and soft segments. [21] Due to excellent abrasion resistance, processability, transparency, recyclability, and mechanical performance, TPU is widely used in automobiles, medical devices, tubes, sporting goods, and decorations. However, its low stiffness, thermal conductivity, and tensile strength may limit its application in some fields. To solve these problems, many researchers prepared TPU-based composites by adding rigid functional materials into the TPU matrix. [22-24] Moreover, the polyethylene glycol (PEG) possessing high affinity with MXene. [25-27] Bera and Maji [24] prepared the graphene/TPU nanocomposites by in-situ solution poly merization technique and studied their mechanical properties, the results demonstrated that the tensile strength of the synthesized nanocomposite was increased by 280% and the toughness was increased by 410% after adding 0.10 wt% graphene oxide. Ning et al. [27] prepared the TPU/ PEG/rGO nanocomposites via melt blending method, and the results showed that there was a great interaction between MXene and the matrix after adding PEG. Rheology is a discipline that studies the deformation and flow of materials under the action of applied stress. The formation of internal network structure, filler dispersion, and interface interaction between filler and polymer matrix can be demonstrated by studying the change of modulus and viscosity. [28-34] Therefore, investigating the rheological properties of TPU/MXene composites is of great significance for evaluating the effect of MXene on the internal structure of composites. To our knowledge, the effects of different MXene content on mechanical, thermal, and rheological properties of TPU composites are rare in the open literature, [18] and we studied the rheological properties of MXene-based composites by melt rheology tests for the first time. In this work, we prepared Ti 3 C 2 T x MXene nanosheets by chemical etching Al atom layer from the layered Ti 3 AlC 2 MAX phase, then pretreated the Ti 3 C 2 T x MXene nanosheets with PEG by solution blending, and Ti 3 C 2 T x MXene/TPU nanocomposites were prepared via melt blending and compression molding. Finally, the mechanical properties, In this work, a novel nanocomposite is prepared via a melt blending of thermoplastic polyurethane (TPU) and Ti 3 C 2 T x MXene nanosheets pretreated with polyethylene glycol. It is found that the tensile strength and elongation at break increased by 41.2% and 15.4% at MXene loading values of 0.5 wt%...

“…High flexibility, tensile strength, oxygen, and aroma barrier properties make them an excellent candidate for use in food packaging applications. [4][5][6] The drawback of PVA is nadir mechanical strength and high hydrophilicity attributable to abundant hydroxyl groups present in the carbon backbone, which makes it exceedingly easy to be plasticized by water, thus limiting its utilization. Graphene oxide with its exceptional properties, including high specific area, chemical resistance, thermal stability, super-mechanical strength has emanated as propitious nanomaterial to ameliorate both the water vapor barrier properties and mechanical properties.…”

Antibiotic resistance is a major threat to public health and food security. Attributable to the heightening occurrence and proliferation of antibiotic‐resistant pathogenic microorganisms, the development of antimicrobial packaging has emerged as a promising technology. Poly (vinyl alcohol) (PVA), a water‐soluble synthetic polymer is contemplated as a promising biocompatible, biodegradable, and low cytotoxic material for various medical, industrial, and commercial applications. To stretch its applications, the polymer material was doped with graphene oxide (GO) decorated with silver nanoparticles (Ag). In this study, an eco‐friendly, facile, one‐step chemical reduction route was employed for the synthesis of nanocomposites by an Ag nanoparticle anchored on GO nanoparticle. The polymer nanocomposite thin film was prepared by solution casting technique. Homogeneity of dispersion and surface morphology was examined by scanning electron microscope investigation. The inclusion of GO‐Ag nanocomposite in the polymer matrix increases the roughness of the film confirmed by atomic force microscopy analysis. The increment in properties was attributable to excellent H bonding between PVA and GO wherein molecules are strongly intercalated with each other. The tensile strength, as well as thermal stability of the PVA/GO/Ag thin films, was significantly enhanced on the incorporation of GO/Ag nanoparticles confirmed by TGA analysis. PVA/GO/Ag nanocomposites exhibited effective antibacterial activity against gram‐positive bacteria Staphylococcus aureus and gram‐negative bacteria Escherichia coli. In contrast, no inhibition around pristine PVA was observed. The prepared films proffered an effective antibacterial activity against contagious microorganisms that qualify them for food packaging and different biomedical applications.

“…Despite the high loadings of filler promote poor mechanical properties, the composite material exhibited a strengthening effect as a result of adding MXene. This enhancement in mechanical properties, is related to the uniform dispersion of the filler and the hydrogen bonds that can form the -OH group between the MXene and the PVA matrix [ 30 ]. Thus, as demonstrated by the digital image in Figure 6 c, the MXene/PSZ-ABN/PVA film retains the flexibility of PVA.…”

Aggregated boron nitride (ABN) is advantageous for increasing the packing and thermal conductivity of the matrix in composite materials, but can deteriorate the mechanical properties by breaking during processing. In addition, there are few studies on the use of Ti3C2 MXene as thermally conductive fillers. Herein, the development of a novel composite film is described. It incorporates MXene and ABN into poly(vinyl alcohol) (PVA) to achieve a high thermal conductivity. Polysilazane (PSZ)-coated ABN formed a heat conduction path in the composite film, and MXene supported it to further improve the thermal conductivity. The prepared polymer composite film is shown to provide through-plane and in-plane thermal conductivities of 1.51 and 4.28 W/mK at total filler contents of 44 wt.%. The composite film is also shown to exhibit a tensile strength of 11.96 MPa, which is much greater than that without MXene. Thus, it demonstrates that incorporating MXene as a thermally conductive filler can enhance the thermal and mechanical properties of composite films.
