The static structure factor (S(q)) of dispersions and gels of disk-like mineral colloids (Laponite) was investigated using time-and ensemble-averaged light scattering. The evolution of S(q) in time after increasing the ionic strength of well-dispersed Laponite suspensions shows that Laponite aggregates and forms fractal clusters. The structure of the aggregates does not depend on the ionic strength, but the rate of growth increases very strongly with the ionic strength. At concentrations below about 3 g/l (0.12% v/v) the aggregates sediment while at higher concentrations space-filling gels are formed. The gels are homogeneous on length scales larger than the correlation length which decreases strongly with decreasing ionic strength and increasing concentration. However, the local structure is the same, independent of the concentration and the ionic strength.

“…We used 0.189 for the refractive index increment of casein at both wavelengths and we used a toluene standard with Rayleigh ratio 2.79 × 10 −5 cm −1 at 532 nm and 1.02 × 10 −5 cm −1 at 685 nm [31][32][33]. When interactions are not negligible one determines the apparent molar mass as: m a = I r (q → 0)/KC.…”

ABSTRACT:The Rayleigh ratio of toluene at 25°C for a wavelength of 632.8 nm was determined by static light scattering measurement of a certified polystyrene reference material PS 2400 with exactly evaluated or certified mass-average molecular mass (M w ). At first, static light scattering measurements were carried out for PS 2400 in toluene with a literature value of the Rayleigh ratio of toluene. Then, corrections of degree of depolarization, density fluctuations, and molecular mass dependence of refractive index increment were applied to the observed M w of PS 2400 to obtain apparent M w . Finally, from the ratio between the apparent M w and the certified M w , the Rayleigh ratio of toluene was reevaluated.
