The zeta potential and the particle size of the cationic PCC and SB suspensions, as well as the final coating formulations, are shown in Table 2. The average particle size of cationic PCC was the same as the anionic PCC (340–370 nm) and polydispersity was1.2.TheanionicPCChasazetapotentialof−27mV,andthe cationic PCC has a zeta potential of+36 mV. The average parti- cle diameter of anionic SB is 130–140 nm, whereas the cationic SB is 210–240 nm, and polydispersity was 1.5. Polydispersity in this paper simply means that the synthesized cationic particles have a broad polydisperse distribution in particle size as both cati- onic PCC and cationic SB have polydispersity > 0.4. This diame- ter indicates latex particle pairs or coalesced pairs are formed, but this size is of the same magnitude as other commercial SB latex [26]. When anionic latex is converted to cationic latex, it under- goes charge neutralization, followed by charge reversal. In this process of reversing charge, the droplets of SB latex undergo coa- lescence [27, 28] and give rise to the larger droplets of cationic
