Summary: With the development of miniaturized and highly integrated microelectronic devices, heat dissipation has become a significant concern. Polymer composites with high thermal conductivity and electrical insulation are promising solutions. However, it remains a challenge to achieve both properties simultaneously. In this study, sandwich-structured PVA/BP-BNNS composite films were fabricated to coordinate thermal and electrical properties, with PVA/BP composite films as the top and bottom layers and the BNNS layer as the middle layer. These films exhibited excellent in-plane thermal conductivity, low dielectric constant, and exceptional breakdown strength, making them potentially useful for heat dissipation in high power electronic devices.

Summary: Surface morphology plays a crucial role in cell attachment and proliferation. Different films with microstructured surfaces made of biodegradable polymers, poly(3-hydroxybutyrate) (PHB) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHB-co-HV), of varying molecular weights were investigated. The study found that stem cells exhibit different behaviors depending on the surface morphology of the films.

Summary: This study proposes a simple approach to endow epoxy resins (EPs) with excellent flame retardancy and high toughness by combining rigid-flexible groups, promoting groups, and polar phosphorus groups with a vanillin compound. The modified EPs achieve a limiting oxygen index (LOI) of 31.5% and reach V-0 grade in UL-94 vertical burning tests with only 0.22% phosphorus loading. The introduction of the P/N/Si-containing vanillin-based flame retardant (DPBSi) improves the mechanical properties of EPs, including toughness and strength, with significant increases in storage modulus and impact strength.

Summary: In this study, a core-shell structured nanoparticle LDH@BP was prepared by adsorbing catechol groups and condensation polymerization between catechol groups and phenylboric acid groups. The LDH@BP was incorporated into epoxy resin (EP), leading to significantly improved flame retardancy and mechanical properties. The EP/LDH@BP nanocomposites achieved a V-0 rating in the UL-94 test at a relatively low content, with an increased LOI of 29.1% and a reduced PHRR of 35.9% in cone calorimeter tests. The mechanical properties of EP/LDH@BP were also satisfactorily improved. These results demonstrate a novel method for constructing efficient and balanced EP nanocomposites with LDHs through the rational design of organic-inorganic nano-hybrid flame retardants.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
