“…The key aspect in nanocomposite structure is the clay-polymer interaction, which affects the dispersion level of clay in polymer matrix. Depending on the dispersion level of layered silicates, the structure can either be separated, intercalated or exfoliated structure [108,[132][133][134][135]. Surface modification plays also important role in achieving good interaction between polymer and clay which affects the extent of dispersion and improves significantly the adsorption as well as removal of dyes or heavy metal ions from water.…”

Their exceptional characteristics and uniqueness make Layered Double Hydroxides (LDHs) and their derivatives promising two-dimensional layered materials that are suitable for several existing and future applications in diverse fields. To name a few, we can mention environmental monitoring and preservation, biotechnology, pharmaceutical and chemical processes, the design and realization of new functional polymers and new magnetic materials with a high-saturation magnetic field, and new composite materials for sustainable concrete infrastructure.The number of research and review articles in high-impact journals highlights the growing attention paid to these materials by not only academic, but also applied-science researchers. This is due to the peculiar properties of LDHs, such as their ease of synthesis even on a large scale, their chemical and thermal stability, their uniform distribution of metal cations, and their ability to intercalate anionic species within the interlayer space and possibly release them, together with their high biocompatibility.This growing interest has led to a parallel growth in the number of publications, some of which appear in this Special Issue of Crystals, presenting both research and review papers. In particular, deeper attention has been paid to innovative synthesis techniques, focusing on those with a low environmental impact, to applications for renewable energy sources, and to interlayer anions' exchange capability for drug release. The ability of Layered Double Hydroxides to form hybrid inorganic/organic nanomaterials is stressed in the review articles.We are confident that reading the articles published in this Special Issue, written by accomplished researchers working for years in the field, will be a source of inspiration to any scientist who studies LDHs within any discipline.

“…The main mechanisms for improving the thermal stability and fire resistance of PMMA nanocomposites are the barrier effects of Cloisite 93A nanoclay, an increase in the mass of the carbon skeleton, an increase in melt viscosity, and gas-phase flame inhibition due to trapping radicals. Cross-linking long polymer chains to form three-dimensional networks is an effective method of improving the mechanical and thermal properties of polymers [ 27 , 28 ]. Phosphorus-containing monomer synthesized in [ 29 ] was introduced into PMMA with radical copolymerization.…”

In the present review, using an integrated approach based on the experimental and theoretical study of the processes of thermal decomposition and combustion of practically important polymers, such as polymethyl methacrylate, polyethylene, and glass-fiber-reinforced epoxy resin, the features of the mechanism for reducing the combustibility of these materials with phosphorus-containing flame-retardants (FR), as well as graphene, are identified. A set of original experimental methods was developed and applied that make it possible to study the kinetics of thermal decomposition and the thermal and chemical structure of the flames of the studied materials, including those with FR additives, as well as to measure the flame propagation velocity, the mass burning rate, and the heat fluxes from the flame on the surface of a material. Numerical models were developed and tested to describe the key parameters of the flames of the studied polymeric materials. An analysis of the experimental and numerical simulation data presented showed that the main effect of phosphorus-containing fire-retardants on reducing the combustibility of these materials is associated with the inhibition of combustion processes in the gas phase, and the effect of adding graphene manifests itself in both gas and condensed phases.
