Thermophysical, Acoustic, and Refractive Properties of Pure and Binary Mixtures Composed of Imidazolium-Based Ionic Liquids and PEG 600

Manzil Patel et al.

Summary: The thermophysical properties of ionic liquids can be controlled by adding suitable co-solvents. In this study, the thermophysical, acoustic, and refractive properties of imidazolium-based ionic liquids mixed with PEG-600 were investigated. The properties were measured and used to calculate excess molar volume, excess molar isentropic compressibility, and deviation in refractive index. Several mixing rules and models were used to analyze the solute-solute and solute-solvent interactions in the mixtures. The results provide insights for fine-tuning the properties of ionic liquids for industrial applications.

Distribution of Carbon Nanotubes in Polycarbonate-Based Blends for Electromagnetic Interference Shielding

Kumari Sushmita et al.

Summary: This study explores the impact of functionalization and distribution of carbon nanotubes (CNTs) in polymer matrices or blends on the electromagnetic interference (EMI) shielding performance of nanocomposites. It is found that despite a decrease in electrical conductivity, ball-milled CNTs may not necessarily lead to a drastic decrease in shielding effectiveness. In addition to the compartmentalization of CNTs, the state, dispersion, and distribution of CNTs also play a significant role in determining the final properties of the composites.

Effect of hydroxyl and carboxyl-functionalized carbon nanotubes on phase morphology, mechanical and dielectric properties of poly(lactide)/poly (butylene adipate-co-terephthalate) composites

Ping Wang et al.

Summary: A series of poly(lactide)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) composites containing different types of multi-walled carbon nanotubes (CNTs) were fabricated. The addition of a multifunctional epoxy oligomer (ADR) improved the compatibility between PBAT and PLA. The introduction of hydroxyl-functionalized CNTs at the PLA/PBAT interface and the inhibition effect of carboxyl-functionalized CNTs on chain extension reaction affected the interaction force between PLA and PBAT. The PLA/PBAT composite with hydroxyl-functionalized CNTs showed stronger interaction and better mechanical and dielectric properties.

Selective Localization of Nanofiller on Mechanical Properties ofPoly(lactic acid)/Poly(butylene adipate-co-terephthalate)Nanocomposites via the Surface Energy and Melt BlendingTechnique

Do Young Kim et al.

Summary: The dispersion and localization of nanofillers in immiscible polymer blends is crucial for fabricating nano-composites with exceptional mechanical properties. This study investigated the effects of melt blending technique and nanofiller surface energy on the dispersion and selective localization of nanofillers in PLA/PBAT nanocomposites. The results demonstrated that controlling the PBAT mixing time could determine the localization of modified silica in the nanocomposite, leading to improved morphology and significantly enhanced tensile strength and elongation at break.

Impact of phosphonium-based ionic liquids-modified carbon nanotube on the microwave absorbing properties and crystallization behavior of poly (vinylidene fluoride) composites

Suellen C. S. M. dos Santos et al.

Summary: Poly(vinylidene fluoride) (PVDF)/multi-walled carbon nanotube (CNT) conducting composites were prepared using melt mixing and dry-mixing methods. Dry-blended composites showed higher conductivity. The formation of beta/gamma crystal in the PVDF matrix was induced by CNT modified with ionic liquids using melt blending. The composite prepared by melt mixing with 0.5 wt% of CNT modified with trihexyl-(tetradecyl) phosphonium bistriflimide showed outstanding microwave absorbing properties.

Mechanically robust and flame-retardant poly(lactide)/poly(butylene adipate-co-terephthalate) composites based on carbon nanotubes and ammonium polyphosphate

Ping Wang et al.

Summary: Multifunctional composites containing multi-walled carbon nanotubes (CNTs), ammonium polyphosphate (APP), and a commercial multifunctional epoxy oligomer (MEO) as chain extender were prepared via melt blending to improve both the mechanical and flame retardant properties of polylactide/poly(butylene adipate-co-terephthalate) (PLA/PBAT) composites. The addition of 6% CNTs and 10% APP in the PLA5-PBAT5/10A/6C composite resulted in optimal flame retardant properties, with a limited oxygen index of 28.3%, decreased peak heat release rate (pHRR) of 368 kJ/m(2), and total heat release (THR) of 72 MJ/m(2). The co-continuous phases in the composite also improved its mechanical properties compared to PLA8-PBAT2 composites.

Poly(butylene succinate) (PBS): Materials, processing, and industrial applications

Massimiliano Barletta et al.

Summary: The development of biodegradable and compostable materials, such as polybutylene succinate (PBS), as alternatives to fossil-based plastics is highly important. PBS is a compostable aliphatic polyester with good mechanical strength and thermal resistance. However, it is often blended with other polymers, fillers, and additives to improve processability and mechanical performance. Recent advances in polymer blending processes have made PBS blends an interesting material platform for applications requiring a balance of mechanical strength, flexibility, thermal resistance, and compostability.

Insights on the catalytic behaviour of sulfonic acid-functionalized ionic liquids (ILs) in transesterification reactions - voltammetric characterization of sulfonic task-specific ILs with bisulfate anions

Maria B. Martini et al.

Summary: This research demonstrates the relationship between the amount of free sulfuric acid and the activity of sulfonic-acid-functionalized ionic liquids as acid catalysts for transesterification reactions. The addition of sulfonic acid groups significantly enhances the catalytic activity of the ionic liquids. These sulfonic acid functionalized ionic liquids act as reservoirs for releasing free acid during the reaction, serving as the actual acid catalyst. The non-sulfonic ILs, on the other hand, show lower catalytic activities at room temperature due to their limited free acid content, which can be improved by raising the reaction temperature.
