Rational design for enhancing mechanical and conductive properties of Ti3C2 MXene based elastomer composites

Soft, Tough, and Thermally Conductive Elastomer Composites by Constructing a Curled Conformation

“…Filled functional elastomer composites have been widely used in a variety of fields due to the functionality of the filler and the softness and toughness of the polymer, such as broadband dielectric materials, electromagnetic shielding materials, and thermal interface materials (TIMs). − However, for TIMs, the pursuit of high functionality (high thermal conductivity) often requires high filler content due to the poor thermal conductivity of pure polymer (0.1–0.5 W·m –1 ·K –1 ). − Unfortunately, too high filler content leads to the decreasing mobility of the polymer chain, which results in enhancing the Young’s modulus and poor toughness. − It is challenging to fabricate comprehensive elastomer composites that combine high thermal conductivity with a low modulus and high toughness.…”

Ti3C2Tx MXene‐Reinforced Natural Rubber Nanocomposites with Tailored Mechanical and Antiaging Properties

“…The unexpected reduction of χ im of NRMX‐0.8 could be attributed to the agglomeration of MXenes in NR matrix. [ 48 ] The glass transition temperature ( T g ) of these nanocomposites varied between ‐66.8 and −65.3 °C, while the lowest T g (−66.7 °C) has been reported by the NRMX‐0. A slight increase of T g can be attributed to the NR molecule immobilization and nanoconfinement effect of MXene.…”

“…Thus, these phenomena could be attributed to the reduced internal mechanical energy loss by the MXene, where the effect is more prominent at high concentrations of MXene. The weak interfacial interaction that leads to slippage of immobilized NR molecules by MXene (Figure 4c) during stretching, [ 48 ] followed by the self‐lubrication effect of MXene, [ 45 ] could be some reason for this effect. Finally, the mechanical properties of MXene/elastomer composites were compared with our findings and given in Table S1, Supporting Information.…”

Research Progress on Two-Dimensional Layered MXene/Elastomer Nanocomposites

“…The tensile strength and elongation at break of SBR/Ti 3 C 2 T x -h-SiO 2 were always higher than those of SBR and SBR/Ti 3 C 2 T x , and the tensile strength of SBR/Ti 3 C 2 -h-SiO 2 with a 4 phr filler increased from 4.09 and 7.52 MPa to 11.21 MPa. Jia et al [ 61 ] solved the stacking problem of MXene sheets by using tetraethyl orthosilicate to grow SiO 2 on the surface of Ti 3 C 2 T x in situ and mixed it with styrene–butadiene latex to prepare a uniformly dispersed SBR/Ti 3 C 2 T x -g-SiO 2 composite. The tensile strength of SBR/Ti 3 C 2 T x with 6 phr filler only increased from 4.09 to 9.05 MPa compared with NBR, and the elongation at break increased from 271% to 461%, while the tensile strength of SBR/Ti 3 C 2 T x -g-SiO 2 with 4 phr filler significantly increased to 14.1 MPa, and the elongation at break increased to 522%.…”
