Ionic liquids grafted with multiwalled‐nanotubes (CNTBr/NTf 2 ), involving hydrophilic bromide salt and hydrophobic bis(trifluoromethanesulphonyl)imide salt, were prepared by amidation, followed by an easy solution‐casting method of blending CNTBr/NTf 2 with sodium polyacrylate (PAA) as well as crosslinking agent (XR‐100) to form PAA hybrid nanocomposites. The uniform dispersion of CNTBr/NTf 2 were analyzed by TEM. The defects and physical properties of fillers were characterized by Raman spectroscopy, Contact angle test, and TGA. Furthermore, microstructures of hybrid nanocomposites were characterized by SEM, from which it can be found that fillers were homogeneously distributed in the PAA matrix. CNTBr/NTf 2 significantly improved the mechanical properties and tensile fatigue resistance, as well as offered tunable swelling behavior of PAA nanocomposites without wasting too much of thermal stability. This study offers a simple approach to develop multifunctional materials based on ionic liquids covalently modified MWCNTs PAA nanocomposites.
