Abstract
A great deal of attention has been given in the last years to the study of the
influence of incorporating nanosized particles and particularly nanoparticles
with a flat-like morphology such as nanoclays or layered double hydroxides,
in the properties of polymer nanocomposites. The high aspect ratio of these
nanofillers could result in improved interactions with polymer molecules at
low filler concentrations, maintaining some of the main advantages of
polymer composites such as reduced density. These improved interactions
could lead to mechanical improvements or enable to regulate polymer
nanocomposites' properties such as transport properties or even improve
their intrinsically low flame retardancy. Recently, polymer foam preparation
and characterization has gained a lot of attention, as foams have been shown
to extend the range of properties and thus possible applications of polymers.
The combination of foaming with the incorporation of nanosized particles
(polymer nanocomposite foams) could further extend the material's
properties, as nanoparticles could have a direct effect in the cellular structure
of the foamed material and thus in its final properties. This chapter pretends
to give a review of the most recent studies carried out on the influence of
layered nanoparticles, focusing on silicate nanoclays and layered double
hydroxides, on the mechanical and flame retardancy properties of polymer
foams, with the final goal of developing multifunctional lightweight
materials with improved properties for applications in sectors such as
construction or automotive.
