The interactions of triblock copolymers (TBP), E30B10E30 and E48B10E48 with ionic surfactants, sodium dodecyl sulphate (SDS) and cetyl trimethyl ammonium bromide (CTAB) were investigated employing steady-state fluorescence spectroscopy (SSF). In this study pyrene was used as probe while cetyl pyridinium chloride (CPC) as a quencher. SSF was used for the calculation of first and third vibronic ratio (I1/I3), aggregation number, binding sites, binding constant and free energy of binding. In the presence of TBP, the I1/I3 was found more for SDS as compared to CTAB, predicting that the micro polarity of the solvent decreases in case of CTAB. The aggregation number of polymer/surfactant mixed systems was determined by SSF techniques. The suppression of the TBP association in the presence of surfactant concentration was also ensured by the same technique.
