Summary: This study successfully prepared strong PP/BF composites with excellent heat deflection temperature and enhanced impact performance, which were improved as the BF content increases. The interfacial bonding properties between BF and PP were significantly improved by PP grafted with maleic anhydride (PP-g-MAH), due to the reaction of maleic anhydride polar groups with the hydroxyl groups on the BF surface. The incorporation of PP-g-MAH led to significant improvements in tensile strength, flexural strength, impact strength, crystallization properties, rheological behavior, and thermal stability of the composites, contributing to the refinement and densification of cellular structure.

Summary: In this study, a one-pot strategy for fabricating SF/CNT films is proposed by designing SF as a modifier of CNTs through non-covalent interactions with the assistance of aqueous phosphoric acid solution. The as-fabricated SF/GL/CNT films showed excellent mechanical strength and high sensitivity, making them suitable for versatile sensors and real-time skin temperature monitoring. This sustainable strategy and the prepared composite films could greatly contribute to the development of electronic skins, personal health monitoring, and wearable electronics.

Summary: Structural modification of PCL allows the fabrication of new functional materials via stretching in ethanol, forming porous structures with pore size below 50 nm. These porous PCL matrices can be used for incorporating additives and preparing functional nanocomposites, biodegradable surgical sutures, packaging materials, and textile vapor-permeable materials. Hybrid NCs with antibacterial and fungicidal activities can be obtained based on the porous PCL matrices and functional components incorporated into them, such as silver, brilliant green, and Betadine.

Summary: The effect of co-doping of layered montmorillonite (MMT) and mesoporous material MCM-41 on the corrosion resistance of PPC-based WPU resin was studied. The results showed that the coatings with MMT and MCM-41 co-incorporation exhibited the best corrosion resistance, attributed to the different interface structure between filler and resin matrix.

Summary: This study reports a strategy to efficiently manipulate carbon nanotube (CNT) networks by forming double networks with branched polyethylenimine (PEI). The double network had high viscoelasticity and ductility, enabling efficient film stretching or creeping for CNT alignment, significantly improving the mechanical strength of CNT films. The viscous drag from the polymer network enhanced the movability of CNTs in reconstructing new networks, resulting in the film's repairability. This double-networking strategy provides a new way to manipulate CNT assemblies for high-performance applications.

Summary: This paper proposes an in situ 3D printing technology of poly-ether-ether-ketone (PEEK)/poly-ether-imide (PEI) hierarchical cellular foam. The foam is lightweight and has a functionalized hierarchical cellular structure in the micrometer scale. The in situ foaming mechanism and optimal process parameters were studied. The foam exhibits low reflectivity and absorption-dominant electromagnetic interference (EMI) shielding properties in the X-band. The lightweight nanocomposite foam manufactured by this technology has great potential in aerospace, high-power instrument protection, and 5G communication products.

Summary: This study fabricated PVA nanofibers reinforced with 1 wt% boron carbide (B4C) using the electrospinning technique. The size and morphology of the B4C particles were found to have a significant impact on the formation and properties of the nanocomposites. The reinforcement of the fibers with sol-gel synthesized nano-sized B4C particles improved the neutron and gamma attenuation of the PVA matrix.

Summary: In this study, waste mussel shells were used to improve the thermal properties of polypropylene monofilaments. The increased filler ratio had a limited effect on the limiting oxygen index, with the lowest intensity loss observed for the monofilament with 5% filler due to a homogeneous dispersion. Furthermore, thermal stability and crystallization temperature of the monofilaments increased with increased filler ratio.

Summary: This study investigated the coating of cotton fabric with huntite-hydromagnesite (HH) or ammonium polyphosphate (APP) solutions as anionic layer and chitosan solutions and nanosols as cationic layer by layer assembly. The growth bilayer number, drying conditions, and anionic layer type affected the flame retardancy and antibacterial properties of the coating. The results showed significant reductions in heat release rate, smoke release, and mass loss rate for fabric samples coated with APP solutions for 15 layers with drying after every dipping process (AP15DE) and fabric samples coated with HH solutions for 15 layers with drying after every dipping process (H15DE). The coatings also exhibited antibacterial activity against E. coli and S. aureus.

Summary: Poly(hydroxybutyrate-co-3-hexanoate) (PHBH) is a biodegradable thermoplastic polyester that shows potential for textile and medical applications. In this study, we aimed to develop a scalable melt-spinning method to produce fine biodegradable PHBH filaments without the need for an ice water bath or offline drawing techniques. We evaluated the effect of different polymer grades and production parameters on the tensile properties of the melt-spun filaments. The results showed that highly oriented non-crystalline mesophase and highly oriented alpha-crystals significantly increased the tensile strength of the PHBH filaments. Aging also had an impact on the structure and tensile performance of the filaments.
