MXene/sPS nanocomposites: rheological, electrical conductivity, polymorphism, mechanical, thermal, and flammability properties.

ABSTRACT: MXenes as an emerging class of 2D materials have great potential in fabricating functional polymer nanocomposites. In this study, Ti3C2T x MXene as a representative MXene filler was employed to prepare sPS nanocomposites. The abundant surface groups (mainly -OH) on MXene allowed facile modification, and thus MXene nanosheets bearing -C12H25 groups were prepared using dodecyl triethoxysiloxane (DCTES) as a modifier. Grafting -C12H25 long alkyl chains onto the surface of MXene strongly affected its affinity towards hydrophobic solvent and the sPS matrix. The rheological threshold concentration (ϕc,G' = 0.033 vol%) and exponent (βG' = 1.51) and the conductivity threshold concentration (ϕc,σ = 0.259 vol%) and exponent (βσ = 2.92) were determined by applying percolation scaling laws.
