Descripción
norganic transition metal dichalcogenide materials (TMDCs), such as tungsten and molybdenum dísulfides (WS2 and MoS2), are of interest to the scientific community, because of their unique layered structure and functional properties, wíth nano~sízed partic1es tending to exhibít a different set of properties compared to the bulk forms. TMDCs nanostructures can be zero-dimensional (O-D) (nanopartíc1es), one-dimensional (l-D) (nanotubes) or two-dimensional (2-D) (nanosheets). In particular, the use of environmenta1ly friendly and biocompatible inorganic fullerene-like nanoparticles (IF- WS2) and nanotubes (INT-WS2) have been shown to offer design, processing, performance and cost advantages when compared to carbon nanotubes, nanoc1ays or other inorganic nanopártic1es/ for manufacturing advanced polymer nanocomposites. The surprising properties ofthese nanostructures such as high impact resistance and superior tribological behavior have shown potential for applications in, for example, the automotive and aerospace industries, electronics and medical technology and, more particularly, in the field of biopolymer nanocomposites. Such applications require the deep understanding of the crystallization hehaviol.lr ofbiopolymers because it Ilffects not only their crystallinc structure and morphology but also their final physical properties. The present research continues work in this field and focuses on the use of well-dispersed INT- WS2 for enhancing the processability and performance ofpoly(hydroxybutyrate-cohydroxyvalerate) (PHBV) . Similarly, good dispersion of INT- WS2 in the poly(L-lactic acid) polymer blends and hybrid bionanocomposites remarkably influenced the thermal, mechanical and tribological properties of PLLA. The novel multifunctional hybrid nanocomposites developed are very promising to be used in the eco-friendly and biomedical applications.
