| Abstract: | The size distribution and morphology of dioctadecyl dimethyl ammonium chloride(TA-100) aggregates in aqueous solution were studied by means of dynamic lightscattering(DLS),transmission electron microscopy(TEM),and rheology.Polarizing microscope(PLM) was used to observe the texture of anisotropic liquid crystal formed in TA-100 aqueous solution.The results show that the average size of surfactant aggregates and rheological property of aqueous solution varies with surfactant concentration.Two relatively long ... |
