Fluorescence Investigations of the Association of PEO-PBO-PEO Triblock Copolymers in the Presence of Ionic Surfactants SDS and CTAB

Zaheer Ahmad, Muhammad Siddiq, Asad Muhammad Khan & Afzal Shah · Advances in Research · 2014

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 prob...
