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.

Summary: Embedding carbon fibers in CNT-PEEK powders can significantly improve the interfacial shear strength between the fiber and the matrix. The interfacial shear strength is negatively correlated with the fiber length, indicating brittle fracture at the fiber-matrix interface. The pulled out carbon fibers are still coated with the matrix, indicating strong adhesion at the interface.

Summary: Flexible PEBA/CNT nanocomposites were fabricated for EMI shielding applications. CNTs nucleated the crystallization of the PA block of PEBA and induced the transformation of the crystals. Reducing the content of the PA block resulted in higher electrical conductivity and improved EMI shielding performances. When ionically conductive polyethylene oxide was used, the hindrance effect of PA crystallization on electrical percolation was effectively mitigated, allowing for high conductivity and enhanced amide dipole moment with a high PA content.

Summary: In this study, PEEK carbon-nanotube (CNT) self-monitoring composites with different levels of filler loading were extruded as 3D-printable filaments. The resulting composites showed varying gauge factor values depending on the filler loading. 3D-printed PEEK 3CNT and PEEK 5CNT composites exhibited piezo-resistive behavior and had average gauge factors of 4.46 and 2.03, respectively.

Summary: It was found that the use of nano-platelet aluminum particles in PET materials not only increased the tensile modulus, tensile strength, and impact resistance, but also significantly improved the flexural modulus. The aluminum platelets could easily become oriented during molding, leading to higher performance compared to talc, mica, and graphene. The aluminum-polyethylene terephthalate (Al-PET) composite is a cost-effective and high-performance combination for making conductive composites.

Summary: Polysulfide polyurethane-urea (PSPU) elastomers with dynamic disulfide bonds were synthesized, and carboxylated carbon nanotubes (CNT) modified with poly-dopamine and KH550 (KPCNT) were used as fillers for the composite films (named KPCNT/PSPU). The self-healing efficiency of KPCNT/PSPU composites reached 98%, and the percolation threshold of KPCNT/PSPU was about twice that of unmodified CNT/PSPU composite film. The excellent dielectric properties of KPCNT/PSPU were attributed to the micro-capacitor effect, interfacial polarization, hydrogen-bonding network exchange, and disulfide bonds within the PSPU.

Summary: This study investigated the effects of CNTs/GNPs hybrid fillers on the properties of PBT/PET composites prepared by melt blending process. The hybrid fillers were found to enhance mechanical properties and thermal conductivity, as well as improve electrical conductivity and EMI SE. Absorption loss was identified as the main mechanism for the attenuation of incident electromagnetic waves in the hybrid composites.

Summary: By using CO2-philic nanoparticles, octatrimethylsiloxy polyhedral oligomeric silsesquioxanes (POSS), the affinity of poly(methyl methacrylate) (PMMA) to CO2 in supercritical carbon dioxide (scCO(2)) foaming can be increased, resulting in improved foaming performance and foam morphology. The composite foams showed smaller average pore sizes and higher pore densities compared to neat PMMA, with the smallest pore diameter and highest pore density achieved under specific processing conditions.

Summary: A new method combining syntactic foam production and supercritical CO2 (scCO(2)) foaming was used to produce bimodal poly(methyl methacrylate) (PMMA) foams with reduced mass density and excellent thermal and sound insulation properties. By processing PMMA composites with hollow glass microspheres (HGMs) and octatrimethylsiloxy polyhedral oligomeric silsesquioxane (POSS) nanoparticles, the bimodal pore structured PMMA-HGM-POSS composite foams were successfully formed. The effects of process pressure, time, and concentrations of HGMs and POSS nanoparticles on the foam morphology were studied, achieving a 69% decrease in foam density with only a 12% decrease in hardness.
