Abstract
We have recently identified a new dispersant for stabilizing ceramic suspensions based on a comb polymer architecture. This additive consists of a poly(acrylic acid) (PAA) backbone with neutral poly(ethylene oxide) (PEO) teeth. This dispersant architecture offers superior performance over a broad range of ionic strength and pH conditions where pure PAA dispersants fail to provide stabilization. Here, we describe the adsorption behavior and rheological properties imparted by PAA-PEO dispersants on the stability of BaTiO3 nanoparticle suspensions at pH 9, using pure PAA as a benchmark.
