similar (6.0 l m) (Table 3). Under our experimental conditions, it was illustrated that the wetting and/or dispersion of talc filler did not accelerate the particle separation.
Similar results were presented by Wallqvist et al. (2009). They showed that the addition of poly(acrylic acid) did not af- fect the measured forces and it does not adsorb to the basal
