Effect of carbon nanotubes on properties of soft materials based on carbon nanotubes-ionic liquid combinations

► Sorption capacities of soft materials with different CNTs have been compared. ► CNTs play a critical role on the stability and sorption capacity of soft materials. ► CNTs, ILs and soft materials have been characterized by Raman spectroscopy. ► Soft materials have been used for SPE of fluoranthene. ► Preconcentrations have been quantified by fluorescence measurements.
