Summary: Studies have shown that the fraction of the secondary filler inducing the maximum synergistic effect decreases with increasing total filler content, leading to an anti-synergistic effect at high fractions. Effective phonon transfer and high thermal conductivity can be achieved at the optimum fraction due to improved filler network formation. The Kim-Jang-Lee model was proposed for both the synergistic and anti-synergistic effects based on the ratio of fillers in the composites.

Summary: A facile strategy for effectively constructing in-plane and through-plane thermal conduction paths in polyimide (PI) and its flexible copper clad laminates (FCCLs) was reported by incorporation of hexagonal boron nitride (h-BN) in a controlled manner. The specific sea-island architecture allowed the preparation of highly thermally conductive flexible PI film and its FCCLs at relatively lower total boron nitride loading. The results of the current work may open a new avenue for promoting the practical application of thermally conductive PI based FCCLs.

Summary: Inspired by the clam-shell structure of pearls, a thermally conductive high-density polyethylene (HDPE) reinforced with two-dimensional boron nitride (BN) filler was successfully fabricated using a rotational shear system. The presence of a shish-kebab structure and aligned BN (002) plane resulted in an increased Vicat softening temperature of 107.9 degrees C, demonstrating excellent heat resistance. The composite with 35 vol% BN loading exhibited the optimal thermal conductivity of 1.26 W/mK and a tensile strength of 40 MPa. This study has developed HDPE/BN composites with effective thermal dissipation and higher service temperature, providing longer service life and reduced material replacement frequency under extreme operating conditions.

Summary: In this study, maleic anhydride (MA) was used to fabricate poly(vinylidene fluoride)/expanded graphite (PVDF/EG) composites via one-step melt mixing. The addition of MA promoted the exfoliation and dispersion of EG in the PVDF matrix, resulting in higher thermal conductivities compared to the PVDF/EG composites without MA. The introduction of MA also increased the melting peak temperature and crystallinity, providing a more efficient method for preparing PVDF/EG composites with high thermal conductivity.

Summary: In this study, a reduced graphene oxide-melamine hybrid was prepared by grafting melamine onto the surface of graphene oxide and subsequent reduction. The hybrid was then used to manufacture a polyoxymethylene/reduced graphene oxide-melamine (POM/rGO-MA) nanocomposite. The incorporation of melamine improved the hydrogen bonding and intercalation of POM molecules in the composite, resulting in a significant decrease in formaldehyde emission and improved thermal degradation properties. The mechanical property of the composite remained stable, and the melt index increased slowly during thermo-oxygen aging. The grafting of melamine onto the graphene oxide surface enhanced the thermal migration resistance of melamine and radical scavenging ability of graphene oxide, leading to an excellent synergistic removal effect of formaldehyde and remarkable oxygen barrier property.

Summary: In this study, bicomponent polymeric architectures were fabricated through visible-light polymerization using methacrylated and PEGylated high oleic sunflower oil (HO-SFO) monomers and compatible polyethylene glycol dimethacrylate (PEG-DMA). The amount of PEG-DMA and PEG units grafted on the HO-SFO backbone directly influenced the key properties of the oil-based polymers, affecting crystallinity degree and PBS absorption capacity. PEG chains acted as mediators for hydrophobic and hydrophilic components, impacting system mobility and network arrangement, leading to higher PBS absorption.

Summary: This paper studies the control, improvement, and correlation of the mechanical and dielectric properties of SEBS and SEBS-MA by using graphite as filler in various concentrations. The results show that the real permittivity increases exponentially with the concentration of graphite, and the dielectric losses are low with high stability at high graphite content. Additionally, an increase in graphite content also leads to an increase in the mechanical stiffness of the composites.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
