The same behavior of the dropwise addition of a PCC sus- pension to a PDADMAC solution was obtained for the dropwise addition of SB latex suspension to a PDADMAC (see Fig. 3). In particular, the SB particles are nano-sized and monodispersed when the PDADMAC: SB ratio is below 0.12:1 wt./wt. (100 mL volume of SB added to the 41.85 mL of 2% PDADMAC). How- ever, the cationic SB particle size (210–240 nm) was larger than the particle size of the anionic SB (130–140 nm). Above a 0.12:1 PDADMAC:SB ratio (above 100 mL of SB suspension added), the SB added dropwise to the solution is now only partially cov- ered by the PDADMAC, leading to bridge flocculation of the system (see Fig. 3). This bridging flocculation resulted in the increased particle size of SB, up to 2–2.2 μm, and a reduction in the zeta potential (+30 to−18 mV (see Fig. 3).
