Solvent-free ionic nanofluids with a core–shell structure were successively synthesized via functionalizing silica nanoparticles with a charged corona and ionically tethering with oligomeric chains as a canopy. It was demonstrated that the as-synthesized nanofluids were endowed with outstanding disp...
