Two‐dimensional Ti3C2Tx (MXene)‐multiwalled carbon nanotubes reinforced ethyl methyl acrylate/ethylene octene copolymer binary blend hybrid nanocomposites with enhanced thermal and dielectric properties

“…Furthermore, its interesting features, including high thermal stability and improved electrochemical capacitance, have recommended it to be used in advanced electronics and energy storage devices that could not be achieved by using these polymers separately. 33,34 We found in our previous work 35 that 15 wt% of conductive Ti 3 C 2 T x exhibited optimum properties, and here we replaced 14.5, 14, 13.5, 13, and 12.5 wt% of Ti 3 C 2 T x with highly conductive MWCNTs. This study provides an auspicious approach to developing hybrid composites for flexible electronic storage materials with improved dielectric permittivity and low dielectric loss.…”

The (002) plane of hexagonal crystal structure corresponds to the Ti 3 C 2 T x -characteristic peak and is considered at 9.18 .…”

“…50 The neat blend displays a single-step mass loss at 388.37 C, which was reported in our previous work. 35 From Figure 5(A), it is evident that the inclusion of filler particles enhances the thermal stability of the neat blend, and the thermal stability improves slightly as the O-MWCNTs percentage is increased in the hybrid nanocomposites. The complete dispersion of the O-MWCNTs throughout the polymer blend is responsible for this improvement.…”

“…The multilayer nano-fillers Ti 3 C 2 T x were synthesized by following our previously reported chemical, acidic etching method. 35 5 g of MAX phase precursors (Ti 3 AlC 2 ) were slowly immersed in 50 mL of 40% hydrofluoric (HF) acid solution in a Teflon beaker and then vigorously stirred at room temperature for 24 h. After a 24-h reaction, the Ti 3 C 2 T x suspensions were rinsed several times until the supernatant liquid was neutral using ethanol and DI water. The sediment was then added into DMSO and bath sonicated for 2 h, followed by centrifugation numerous times with DI water and absolute alcohol for 1 h at 8000 rpm.…”

“…This behavior indicates that Ti 3 C 2 T x and O-MWCNTs have produced persistent conductive channels above the percolation. 35 As a result of the dielectric behaviors of the hybrid nanocomposites and the conductive nature of the Ti 3 C 2 T x and MWCNTs make them suitable as a base material for the fabrication of lightweight and extremely efficient energy storage devices. In this study, a simple solution casting procedure was utilized to prepare the highly flexible EMA/EOC/Ti 3 C 2 T x / MWCNTs dielectric hybrid composites at different weight proportions of Ti 3 C 2 T x and MWCNTs hybrid into the EMA/EOC binary blend with high dielectric permittivity and low loss, as well as a good combination of thermal and conductivity properties.…”
