Summary: Methods for fabricating super-liquid-repellent surfaces have traditionally relied on perfluoroalkyl substances, but concerns over their environmental and health effects have sparked interest in fluorine-free alternatives. Polydimethylsiloxane (PDMS) is a promising candidate, although it only exhibits superhydrophobicity instead of liquid repellency. In this study, we demonstrate that a well-designed two-tier structure of silicon dioxide nanoparticles and surface-tethered PDMS chains can achieve super-liquid-repellency towards low surface tension liquids. Our work highlights the feasibility of scalable fabrication methods and environmentally friendly surface functionalization for fluorine-free super-liquid-repellent surfaces.

Summary: The addition of cellulose nanofibers (CNFs) significantly reduced the half-crystallization time of the PLLA/PDLA blend, and when 3% modified CNFs were incorporated, almost exclusively SC crystallites were formed with no HC crystallite presence. This was speculated to be due to enhanced interchain molecular interactions between CNFs and PLA, presenting a feasible and efficient method for producing high-performance PLA materials with exclusively SC crystallites.

Summary: In this study, modified PLA beads are foamed using one-step, anhydrous supercritical CO2 extrusion, which significantly reduces production time and prevents pyrohydrolysis of PLA while avoiding wastewater generation. The use of a chain extender increases the melt strength of PLA. The PLA bead foam obtained by extrusion foaming with wind-cooling pelletizing technology exhibits a high expansion ratio, typical cellular morphology, and glossy surface. This research is beneficial for the continuous preparation of PLA bead foam and other polymer beads such as PS and PP, with applications in green packaging, sound absorption, cold-chain logistics, and more.

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.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. 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.
