Rhizome into Polylactide to Obtain Green Composite, Polymers, ISSN: 2073-4360, DOI: 10.3390/polym16152169, Vol.16, No.15, pp.2169-1-20, 2024 Streszczenie: This study showed that a polylactide (PLA)-based composite filled with nanostructured hydroxyapatite (HAp) and a natural extract from the rhizome of Curcuma longa L. could provide an alternative to commonly used fossil-based plasticsfor food packaging. The incorporation of HAp into the PLA matrix had a positive effect on improving selected properties of the composites; the beneficial effect could be enhanced by introducing a green modifier in the form of an extract. Prior to the fabrication of the composite, the filler was characterized in terms of morphology and composition, and the composite was then fully characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman and Fourier transform infrared spectroscopy (FT-IR), and the mechanical, thermal, thermomechanical, and optical properties were investigated. The proposed material exhibits antioxidant properties against DPPH radicals and antibacterial performance against Escherichia coli (E. coli). The results showed that the nanocomposite has the highest antioxidant and antibacterial properties for 10 wt% HAp with an average diameter of rod-shaped structures below 100 nm. In addition, the introduction of turmeric extract had a positive effect on the tensile strength of the nanocomposites containing 1 and 5% HAp. As the resulting material adsorbs light in a specific wavelength range, it can be used in the medical sector, food-packaging, or coatings.

Fortunately, LIBs can be recycled and are already a valuable source of metals. This work is focused on the properties of the spent LIBs powder, which is a postproduct of the proposed organic leaching process and is presented as a source of nanocarbons with a unique structure. Furthermore, attention is paid to revealing the properties of the carbon component that can find a second life in other applications like photocatalysis or sorbents. Raman spectroscopy is used for the characterization of graphitic carbon. Scanning electron microscopy images are numerically quantitatively analyzed to provide additional parameters (for instance, the total length of edges) about the structure of materials, and X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS) further check their composition.
