| Abstract | We have used ultra-small-angle scattering (USANS) and fluorescence microscopy to demonstrate the existence of a nonfractal large-scale structure in attractive micellar gels of poly(styrene)-poly(acrylic acid) block copolymers, which have some characteristics of attractive colloidal glasses. The nature of the large-scale structure appears to depend systematically on the strength of attraction. Our systems display scattering that follows I approximately q(x) in the low q regime, with x varying from approximately -3 to -4 as the strength of attraction is decreased. This scattering behavior appears to be the result of surface scattering from large, highly polydisperse aggregates with rough interfaces. |
