Cellular nanocomposites are a novel class of cellular materials that include at least one phase (typically inorganic) with size in the nanometric range. Nanoparticles are known to play a multifunctional role in cellular materials as they are able to act at both micro and macrostructural levels. They can enhance nucleation and also improve the thermal, mechanical or barrier properties of the polymer comprising cell walls. However, the potential improvements that are associated to the presence of the nanoparticles are conditioned to achieve proper levels of dispersion and compatibilization between them and polymeric matrix.
CellMat Laboratory has been working with cellular nanocomposites based on different types of nanoparticles (montmorillonite, silica nanoparticles, carbon nanotubes, carbon nanofibers, graphene, sepiolites, etc.) that have been infused in different types of polymeric matrices (PE, PP, PS, PU, PMMA, PC, etc.).
