Summary: In this study, six nanocomposites based on different magnetic nanoparticles and a conducting polymer, poly(3-hexylthiophene-2,5-diyl) (P3HT), were synthesized. The nanoparticles were coated with either squalene and dodecanoic acid or P3HT, and the cores of the nanoparticles were made of nickel ferrite, cobalt ferrite, or magnetite. The average diameters of all synthesized nanoparticles were below 10 nm, with varying magnetic saturation at 300 K. The impact of different magnetic fillers on the conducting properties and the influence of the shell on the final electromagnetic properties of the nanocomposite were explored.

Summary: Nanocomposites based on NBR and EPDM (50/50) filled with different concentrations of nWMF were prepared, and their properties were investigated. The addition of nWMF improved the miscibility and thermal stability of the nanocomposites. The mechanical properties, including torque, cure rate, and reinforcing factor, increased with the incorporation of nWMF, while the optimum cure and scorch time decreased. The nanocomposite with 40 phr of nWMF showed promising mechanical and dielectric properties for insulation and antistatic purposes.

Summary: The study fabricated nanocomposites with aligned graphene platelets by incorporating them into an epoxy matrix through mechanical mixing and sonication, followed by applying an electric field to align the platelets before curing. Experimental results showed that the nanocomposites with aligned graphene exhibited higher tensile moduli and strength compared to those with randomly oriented graphene. In addition, nanocomposites with functionalized graphene showed superior interfacial and mechanical properties when compared to those with reduced graphene oxide.

Summary: This study aimed to enhance the physicochemical properties of the green polymer chitosan (CS) to provide alternative usage areas. A compatible blend of CS (CS-PFPAMA) with a synthetic polymer poly 2-(4-fluorophenyl)-2-oxoethyl-2-methylprop-2-enoate (PFPAMA) was prepared by hydrothermal method. Lanthanum hexaboride (LaB6) nanoparticles (NPs) were successfully added to the CS-PFPAMA blend, and morphological and thermal characterizations were performed. The nanocomposites showed increased dielectric properties and exhibited resistance against Escherichia coli and Staphylococcus aureus pathogens.

Summary: The antibacterial properties of nanosilver polyethylene packaging are important in the field of food packaging. The crystalline structure of the materials affects the migration of nanosilver in polyethylene, thus impacting its antibacterial rate. By preparing nanosilver/polyolefin composite films through melt blending, it was found that materials with higher melt index have better fluidity and higher antibacterial rate. Nanosilver is uniformly dispersed in the substrate and can increase the long period without affecting the crystalline region. Higher density polyethylene has thicker lamellae and lower antibacterial rate, while materials with lower crystallinity exhibit higher antibacterial properties. The introduction of silver nanoparticles slightly increases the crystallinity of the composites and improves their optical properties.

Summary: Functionalized graphene-polymer nanocomposites have been widely studied for their enhanced properties, but their current applications are limited by the multi-step processes or hazardous reducing agents required for functionalization. This study presents a single-step method for synthesizing thermally reduced graphene oxide (TrGO) using shellac, which shows promise for potential applications in biomedical devices. At a filler loading of 1.5%, the PVA-TrGO nanocomposite exhibited significantly improved mechanical and thermal properties, as well as enhanced antibacterial effectiveness compared to neat PVA.

Summary: This study outlines the fabrication and characterization of pamidronate (PDS) embedded nanofibrous scaffolds based on polycaprolactone/polycaprolactone-polyethyleneglycol-polycaprolactone (PCL/CEC) blends for osteoporotic bone defect management. The electrospinning technique was utilized to fabricate PDS-loaded scaffolds, and the effect of PDS on the blends was evaluated in terms of surface morphology, wettability, biodegradability, and in vitro cytocompatibility. The results showed that the PCL/CEC-PDS scaffolds had a fibroporous architecture, appropriate mechanical properties, and the ability to support cell growth, indicating their potential for managing osteoporotic bone defects.
