Summary: The effect of lithium titanium oxide nanoparticles (Li4Ti5O12 NPs) on the optical and electrical performance of polyether sulfone (PES) nanocomposite films was investigated. The interaction between PES and Li4Ti5O12 NPs was confirmed by XRD and FT-IR. The addition of Li4Ti5O12 NPs increased the crystallinity of PES and formed charge transfer complexes. The results suggest that Li4Ti5O12 NPs are a promising dopant for improving the electrical properties of PES and have potential applications in various fields.

Summary: The current packaging materials market is dominated by single-use plastics derived from petrochemicals, which are inexpensive and environmentally stable. However, these plastics pose a threat to the environment as they are rarely recycled and often end up in landfills or littered in the environment. Nature-derived and biodegradable polymers offer potential alternatives, but their barrier properties fall short compared to traditional plastics. Therefore, there is a need to enhance the barrier properties of sustainable polymer systems through chemistry and processing technology. This review summarizes the important contributions and advancements in improving the gas and moisture barrier properties of sustainable polymer systems for packaging applications, including microstructure tuning, surface energy modification, morphology control, and self-assembly.

Summary: In recent years, the use of nanomaterials, particularly carbon nanotubes, in cement-based composites has attracted considerable attention due to their potential in monitoring civil structures and infrastructures. However, the challenge lies in dispersing the nanotubes effectively and efficiently, which is typically addressed using sonic treatments or surfactants. This study aims to analyze the self-sensing properties of cementitious composites developed with NaOH as the dispersing agent, and the findings suggest that the dispersing strategy using NaOH is promising for enhancing the sensing properties of the composites.

Summary: In this study, two hybrid hydrogel systems were synthesized using two crosslinking methods: physical (ionic gelation) and chemical (radical polymerization). The chemical method (H-A-GO(C)) resulted in hydrogels with higher swelling degree and pronounced pH responsivity, while the physical method (H-A-GO(P)) led to degradation under external voltages. The release profiles of the hybrid hydrogels, extensively analyzed using mathematical models, showed sustained drug release and the ability to modulate the release amount and rate by electro-stimulation of H-A-GO(C).
