Abstract

Over the past decade, special attention has been paid to layered double hydroxides (LDH) as potential nanofillers for polymers. Basic inorganic layers of LDHs are positively charged; thus they complement the negatively charged silicate layers and may serve as a route for the introduction of anionic functionalities as modifiers in the filler structure. Most of the investigated LDHs are of synthetic origin and consequently of high purity, which presents an advantage in comparison with naturally occurring fillers. The properties of LDHs may be varied in a wide range by the adequate choice of metal cations and counteranions. This paper gives an overview of the recent investigations into layered double hydroxides as polymer nanofillers, and describes the filler synthesis and characterization procedures as well as procedures for the incorporation of fillers within polymer matrices.
