Recently, great successes have been garnered in the electronics segment, such as the development of printed circuit panels, miniaturized and critically integrated light-emitting gadgets, aerospace, maritime, and automotive components. However, the generation of excessive heat and elevated fire risks of these gadgets is escalating resulting in they gadgets malfunctioning, degradation, minimized performances as well as high prevalence rate of fire outbreak. Hence, materials exhibiting thermal conductivities and flame retardancy are emerging to be essential components in electronic gadgets as well as other engineering materials due to effective heat dissipation sustaining safe operational temperature as well as fire retardancy in case of fire outbreaks. Despite advantages of polymeric nanocomposites (PNC) in heat dissipation applications, such as electrical insulation, facile processability, low-weight, and low-cost, they are not appropriate for high-performing gadgets due to inferior thermal conductivities (0.2-0.5 W/mK) and high prevalence rate of flammability. Thus, numerous approaches have been engaged to embed thermally conductive and flame retardant fillers such as M-X, carbon derivatives, metallic, as well as ceramic substrates within the polymeric matrices to inculcate heat conductivity and fire resistance to them. MXene (M-X), a novel set of 2-D materials is currently garnering significant research attention because they have shown high prospects for use in electronic gadgets, batteries, and supercapacitors (SCs). Therefore, this paper present recently emerging trends in thermal conductivity (TC) and flame retardancy of M-X@polymeric nanoarchitectures (M-X@PNC).
