“…This occurred because of the softened epoxy surface, which resulted in a change in the morphology and a rearrangement of the MXene flakes. In addition, no degradation of Ti 3 C 2 T z could occur, according to previous thermogravimetric analysis [ 49 ], which shows that the MXene is thermally stable and loses only 4–7% of its weight at 700 °C.…”

“…Notable changes in the relative resistance curves for all the samples appeared between strains of 0.5% and 1.1% ( Figure 5 b). Previous research on pure MXene films under tensile conditions yielded similar fracture strain values, which are marked in the figure as MXene fracture points (FP): FP-1 [ 48 ], FP-2 [ 49 ], and FP-3 [ 42 , 43 ]. These results suggest that MXene flakes began to debond from one another as the resistance began to increase drastically.…”

Real-time strain monitoring of large composite structures such as wind turbine blades requires scalable, easily processable and lightweight sensors. In this study, a new type of strain-sensing coating based on 2D MXene nanoparticles was developed. A Ti3C2Tz MXene was prepared from Ti3AlC2 MAX phase using hydrochloric acid and lithium fluoride etching. Epoxy and glass fibre–reinforced composites were spray-coated using an MXene water solution. The morphology of the MXenes and the roughness of the substrate were characterised using optical microscopy and scanning electron microscopy. MXene coatings were first investigated under various ambient conditions. The coating experienced no significant change in electrical resistance due to temperature variation but was responsive to the 301–365 nm UV spectrum. In addition, the coating adhesion properties, electrical resistance stability over time and sensitivity to roughness were also analysed in this study. The electromechanical response of the MXene coating was investigated under tensile loading and cyclic loading conditions. The gauge factor at a strain of 4% was 10.88. After 21650 loading cycles, the MXene coating experienced a 16.25% increase in permanent resistance, but the response to loading was more stable. This work provides novel findings on electrical resistance sensitivity to roughness and electromechanical behaviour under cyclic loading, necessary for further development of MXene-based nanocoatings. The advantages of MXene coatings for large composite structures are processability, scalability, lightweight and adhesion properties.

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%...
