Abstract

Abstract: In this paper,1-naphthol has been used as a fluorescence probe to investigate the hydrophobic microdomain structure formed by hydrophobically modified polyacrylamide in aqueous solution.It was found that 1-naphthol molecules are soluble in spherical SDS micelles but insoluble in the hydrophobic microdomains of AM-co-HDMAM.The solubility difference indicated that,owing to the steric hindrance of polymer backbone,the hydrophobic microdomains of AM-co-HDMAM should have a less integrated micellar structure than SDS micelles.

Key words: Naphthol, Polyacrylamide, Hydrophobic microdomain
