Natural polymer is a frequently used polymer in various food applications and pharmaceutical formulations due to its benefits and its biocompatibility compared to synthetic polymers. This study revealed the benefits of incorporation of Sep-MBE hybrids into the alginate films and their potential application as active packaging films or coating material. The release kinetics results of MBE polyphenols from the active films into alcoholic food simulant indicated that the addition of Sep-MBE hybrids to alginate film is able to slow the release of MBE poly-phenols. The antioxidant activity of the films was significantly improved and raised with increasing content of MBE. The results suggested that incorporation of Sep-MBE hybrids into the films improved elongation at break, tensile strength, water vapor and UV barrier properties compared to the control film. Fourier transform infrared (FTIR) spectra indicated that strong interactions between the polyphenols present in the MBE and sepiolite were involved in the films. The effects of different extract concentrations on the film properties were determined by measuring physicochemical, mechanical and antioxidant properties of the films. Sepiolite showed a remarkable synergistic effect on the retention of Nd3+ ions, being promising asīiosorbents for the effective and selective recovery of neodymium from aqueous media.Īlginate nanocomposite films incorporating sepiolite (Sep) modified with myrtle berries extract (MBE) rich in polyphenols were prepared by solution casting method. Solutions, with the polysaccharide chains arranged as liquid crystals, and involving around 27% (w/w) of In fact, only those materials prepared from concentrated sacran Sacran–sepiolite materials show a clear preference for Nd3+ ions over Ce3+,Įu3+ and Gd3+, and the results confirm the influence of the conformation of sacran chains in crystallineĭomains on the adsorption properties. Profiting from the well-known adsorption properties of sepiolite and the ability of sacran to complex rareĮarth and heavy metal ions. These materials can act as adsorbents of lanthanide ions, Resistance and integrity in aqueous solutions. Sacran–sepiolite films show tensile moduli about twice that of neat sacran films, and improved This work introduces novel bionanocomposites based on theĪssembly of sacran to sepiolite, a fibrous hydrated magnesium silicate, reporting some of their specialįeatures. Sacrum, is an interesting biopolymer for developing functional clay-based bionanocomposites due to itsĬolloidal and metal complexing properties.
