Additive induced core and corona specific dehydration and ensuing growth and interaction of Pluronic F127 micelles.

Highlights: [•] The effects of butan-1-ol and NaCl on the przoperties of F127 micelles were studied. [•] These two substances bring about site specific dehydration of F127 micelles. [•] Dehydration of micellar core by butan-1-ol leads to sphere-to-rod micellar growth. [•] Corona specific dehydration by NaCl induces inter-micellar attractive interaction. [ABSTRACT FROM AUTHOR]
