“…As a result, it was considered that incorporating GEO and SiO 2 NPs would be more effective in preventing pathogenic microorganisms. The antibacterial properties were confirmed and justified by the previous research work with PBAT/SiO 2 and PVA/SiO 2 composite films [42,43]. The antibacterial properties of SiO 2 NPs were found to be proportional to their total surface area.…”

Active packaging material has been used in the food industry to maintain the quality of packaged foods. The use of conventional polymers has serious environmental consequences due to improper disposal or recycling methods. Therefore, active packaging films based on biopolymers have been developed due to their excellent biocompatibility, degradability, and eco-friendliness. Amongst all essential oils, grape seed oil is considered to be a promising antimicrobial agent. It comprises large quantities of flavonoids, tocopherols, and other antimicrobial compounds. Grape seed essential oil has good antimicrobial and antioxidant activity. As a film, it is used to preserve food items such as poultry products, fish, and tomatoes. This work aimed to develop a polybutylene adipate terephthalate (PBAT) biocomposite film incorporated with natural grape seed essential oil (GEO) in addition to silica nanoparticles (SiO2 NPs) using the solution casting process. To achieve the desired packaging properties of the prepared PBAT-based film, the concentrations of grape seed essential oil as a plasticizer and nanosilica as a filler material were varied. The optical, physical, barrier, mechanical, surface hydrophobicity, and antibacterial properties of the PBAT/GEO/SiO2NP films were assessed. The FT-IR and XRD results indicated that GEO had effective miscibility with the PBAT/SiO2NP matrix. The addition of GEO increased the film flexibility, opacity, and antimicrobial activity, but the incorporation of SiO2NPs in the PBAT/GEO blend increased the tensile strength, thermal stability, and antimicrobial activities. The PBAT/GEO/SiO2NP films exhibited excellent antibacterial activity against food spoilage microorganisms. Finally, due to improved antimicrobial activities, film flexibility, optical, and heat resistance properties, the PBAT/GEO/NP nanocomposite films were found to have high potential for usage in active food packaging applications.

“…The doping of Co‐OPB in PVA minimizes the stress concentration thereby enhancing the tensile modulus behavior. [ 30 ] Figure 7 (A–D show the SEM image of carbon fiber and cobalt particle toughened PVA composite. The reinforcements are showing a highly reacted phase with the PVA matrix due to the highly porous structure of biochar particles.…”

This present study discusses the effects of doped novel cobalt-onion peel-based water soluble Poly vinyl alcohol (PVA) composite for its electromagnetic interference shielding (EMI) effectiveness in high-frequency bands such as X and Ku region. The primary aim of this study was to prepare a flexible electromagnetic shielding material for protecting electronic gadgets from the EMI effect. The biochar particles were prepared from red onion peel and mixed with cobalt/chopped carbon fiber (CCF) to form a compound structure. According to the results, the biochar and CCF addition improved the relative permittivity up to 9.6. Similarly, the hysteresis analysis showed a broad "S" curve for 2 vol % cobalt-added PVA composite. Moreover the doped composites are better in mechanical properties and the highest tensile strength of 79 MPa with Shore-D hardness of 37 was noted for PV3 composite designation. Finally, the highest wave shielding of À44.37 dB and À 49.62 dB for X and Ku band were observed for composite designation PVA4. This EMI shielding effectiveness improved composites could be used as shielding material for modern industrial, defense, and medical applications.

“…By analyzing Figure 3 a, it is possible to observe that Ecovio ® (Ecov) presents characteristics of both polymers that constitute it, so the graphic shows a large amorphous halo and diffraction peaks at 16.2°, 17.4°, 20.4°, 23.1° and 24.9°. The literature reports that the crystalline phase of the PLA presents the diffraction angles in approximately 16.2° and 17.4°, referring to the planes (110) and (203) [ 46 , 47 ]. However, Arruda et al (2015) [ 48 ] related the peaks in values close to those found in this study to basal reflections of the planes (010), (111), (100) and (111), characteristic of the PBAT crystalline phase that eventually overlapped the crystalline phase of the PLA.…”

Development of Biodegradable PLA/PBAT-Based Filaments for Fertilizer Release for Agricultural Applications

et al. 2022

The aim of this work was to produce filaments of PLA/PBAT and NPK fertilizer adsorbed on organophilized bentonite intended for application in the prototyping of biodegradable agricultural artifacts in 3D printing, using the Fused Deposition Modeling (FDM) technique. This is the first time that we have reported this composite for a 3D printing approach. Systems containing PLA/PBAT, organobentonite and NPK were initially processed in an internal mixer and later extruded as filaments in a single-screw extruder. The prototypes were printed by FDM. Structural, morphological and thermal properties, as well as NPK releasing, were investigated. The results suggest that exfoliated and/or intercalated nanocomposites were obtained by the organoclay addition to the PLA/PBAT blend. The morphological analysis revealed a good surface quality of the impressions. Systems containing organobentonite released approximately 22% less fertilizer in 24 h compared to the systems without organobentonite. This difference is due to the higher concentration of nanoparticles that generate more barriers to the diffusion of NPK. The release data for these systems had a better fit to the kinetic model of Korsmeyer-Peppas. Thus, studied filaments have the potential to retard the release of fertilizer and are suitable for further development of structures for agricultural applications by FDM.
