Pyrene was used as a fluoresecent probe to investigate the polarity and stability of the micelle of anionic aqueous polyurethane dispersion (AAPUD).Results indicated that the micelle is non-polar or weak polar
and the polarity is greatly dependent on the hydrophilicity of the main chain of polyurethane and the pH value of the medium.The polarized value of the polarized fluorescent of pyrene in the AAPUD was measured
and the results show that the stability of the micelle could be characterized by the polarized value.
