The results showed that the thermal conductivity of the composites increased to 0.5444 Wm(-1) K-1 at 30 wt% filler content, with a 22.89% increment compared to PEN copolymer without additive. The PEN/h-BN composite exhibited excellent thermal properties and improved dielectric constant and insulation performance. The tensile strength was 62.3 MPa and the elastic modulus was 3567.5 MPa. In conclusion, the 30 wt% h-BN/PEN composite prepared in this research has great potential and promising prospects in the field of electronics.

Summary: In this study, a high-performance functional polymer called poly(arylene ether nitrile) (PEN) was used as a novel organic corrosion protection coating for P110 steel. The introduction of phenyl silane functionalized hexagonal boron nitride (h-BN-MPDTS) into PEN improved the corrosion resistance of the coating. The impedance of the h-BN-MPDTS PEN coating increased by two orders of magnitude compared to the neat coating, and remained stable throughout the 80-day immersion process. Additionally, fewer signs of rust were observed on the h-BN-MPDTS sample during the salt spray experiment, demonstrating its superior corrosion resistance.

Summary: The addition of hexagonal boron nitride fillers into poly(vinyl butyral) coatings improves the corrosion protection performance of copper due to non-covalent interactions between the fillers and PVB molecules. The BN-reinforced PVB coating shows significantly higher corrosion resistance compared to pristine PVB coating, providing a long-term protective barrier for the copper substrate. Increasing the loading of h-BN fillers in PVB enhances the corrosion protection performance without accelerating copper corrosion when the coating is damaged.

Summary: Hexagonal BN fiber coatings and powders were prepared by pyrolysis of boric acid and urea in a hydrogen and nitrogen atmosphere. The appropriate mixing ratio of raw materials for desired BN composition and crystal structure was investigated, resulting in hexagonal BN with near-stoichiometric composition. Coatings applied on SiC filaments showed crystalline BN layers without significant bridging in fiber bundles, as confirmed by SEM/EDS and grazing incidence x-ray diffraction analysis.

Summary: This study investigates the thermal degradation mechanism of poly(ether ketone ketone) (PEKK) in the melt-state in air using molecular dynamics simulations, X-ray photoelectron spectroscopy, and rheology. The study reveals that the ether linkages in the PEKK backbone have the lowest bond dissociation energies and preferentially undergo chain scission. The rheological properties of PEKK are highly influenced by exposure time in the melt-state and angular frequency.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
