XPS, SEM, DSC and Nanoindentation Characterization of Silver Nanoparticle-Coated Biopolymer Pellets

The development of environmentally friendly materials has been the focus many research groups in recent years due to increased harmful effects plastics on environment. Bio-based are considered a key solution from sustainable manufacturing perspective. nano-coating biopolymer blends with silver nanoparticles is subject challenging projects line EU Directive environment protection and manufacturing. Coating biopolymers provides an antimicrobial antiviral active surface. In this work, we develop nanoparticle-coated Arboblend V2 Nature pellets. main goal obtain new material antibacterial action obtained blending pellets through physical vapor deposition. study divided three steps. first step represents characterization coated/raw second involves injection molding nano-coated samples obtained. last regards press coated order thin films, as well their characterization. PVD-sputtering technique used coat nanoparticles. This process especially optimized for coating raw high water content small-size mechanical properties, surface chemical composition thermal properties both virgin measured analyzed resistance layer. Differential scanning calorimetry, electron microscopy, X-ray photoemission spectroscopy nanoindentation testing performed. calorimetry test detects no significant alteration produced PVD confirms viable application nano-silver–biopolymer composite products.
