[4]In the presence of electrolytes, the stability of the PAA-a-Al203 suspension is weakened with increasing ionic strength, which is a result of the steric barrier screened by counter ions. In addition, the destabilizing effect, induced by the Ca2+ ions, is found to be more pronounced than the destabilizing effect of Na+ at the same ionic strength. [5]For PAA-PEO¡ªa-A1203 suspensions, adding electrolytes does not cause the reduction of flowability, and the system stability is not sensitive to salt ions. The existence of a charge-neutral PEO segment is mainly responsible for this anti-electrolytic performance. |
