Layered double hydroxides (LDHs) can be incorporated in a variety of composites with different structures and
properties. The choice of synthesis method is a very important factor in achieving LDHs with the desired structure and
properties. A method involving separate nucleation and aging steps (SNAS), layer-by-layer self-assembly methods, in situ
surface synthesis methods and a clean method have been developed in recent years. LDHs with different structure and
properties have been synthesized using these different methods. Applications of these LDHs include as environmentallyfriendly
functional additives in cement and asphalt, as new catalytic materials, as novel optical materials, in biosensors
and as superhydrophobic materials. This paper summarizes recent patents describing methods for synthesizing LDHs with
tailored structures and properties.
