Researchers at the ARC Centre of Excellence for Functional Nanomaterials have developed a
method to prepare layered double hydroxide (LDH) particles of controlled and narrow particle size
distribution. The novel method also prevents the aggregation of the particles therefore facilitating the formation of a clear suspension.
LDH is plate-like (Figure 3) mixed metal hydroxide particle that through ionic
attraction forms layered or sandwich like particles. The outer cationic LDH plate with their excessive positive charge has interlayer anions to balance the ionic charges.
