The anisotropic nature of the shear-field renders the microstructure highly anisotropic, leading to dichroism. Experiments on the dichroic behavior can thus be used to test theoretical predictions on microstructural order under shear flow conditions. We performed both static and dynamic dichroism and turbidity measurements on a colloid-polymer mixture, existing of silica spheres (radius 51 nm) and polydimethylsiloxane polymer (molar weight 204 kg/mol). Sufficiently far away from the critical point, in the mean-field region, the experimental data are in good agreement with theory. Very close to the critical point, beyond mean field, for which no theory exists yet, an unexpected decrease of dichroism on approach of the critical point is observed. Moreover, we do not observe critical slowing down of shear-induced dichroism, right up to the critical point, in contrast to the turbidity. 000027238 536__ $$0G:(DE-Juel1)FUEK53$$2G:(DE-HGF)$$aPolymere, Membranen und komplexe Flüssigkeiten$$c23.30.0$$x0 000027238 588__ $$aDataset connected to Web of Science 000027238 650_7 $$2WoSType$$aJ 000027238 7001_ $$0P:(DE-Juel1)130616$$aDhont, J.
