Summary: This study investigated the flame-retardant effect of transparent epoxy coating with aluminum hypophosphite nanoparticles on polylactic acid sheets. The addition of these nanoparticles into the epoxy resin accelerated the degradation of the coating, resulting in increased char residue. The presence of the nanoparticles reduced the peak heat release rate significantly, leading to the formation of a homogeneous char layer with a 15 wt.% nanoparticle content. However, further increase in content did not enhance the flame-retardant properties due to the formation of structural cracks in the coating.

Summary: Three types of Pt/CeO2 catalysts (rod-shaped (CeO2-R), cube-shaped (CeO2-C), and octahedral-shaped (CeO2-O)) with different support morphologies were synthesized and investigated for catalytic oxidation of C2H4 at low temperatures. The catalysts showed shape-dependent catalytic activity, with Pt/CeO2-O exhibiting the highest activity. This can be attributed to the different oxygen species activated by the catalysts in the C2H4 oxidation process. Additionally, the negative impact of water condensation on the catalyst can be eliminated by refreshing the catalyst with N2 purging. Overall, this work provides a novel catalytic system for efficient low-temperature ethylene oxidation and enhances our understanding of the catalytic mechanism.

Summary: In 2019, Flame Retardancy Index (FRI) was introduced as a universal index for classifying flame-retardant polymer materials. FRI quantifies the flame retardancy performance on a logarithmic scale based on peak Heat Release Rate (pHRR), Total Heat Release (THR), and Time-To-Ignition (t(i)) from cone calorimetry data. It has proved to be reliable for ranking polymer materials in terms of flame retardancy performance over the past four years. Additionally, new variants and the Flammability Index (FI) based on Pyrolysis Combustion Flow Calorimetry (PCFC) data were defined to further analyze the relationship between FRI and FI.

Summary: Chitosan, as a natural green polymer, shows potential as a plastic replacement. However, the strength and toughness of chitosan limit its commercial use. By constructing a sacrificial conjoined-network, a high-performance lignin/chitosan composite film was successfully fabricated, which simultaneously improved tensile strength, elongation, and toughness. The composite film also exhibited excellent UV resistance, thermal stability, low oxygen permeability, and food preservation qualities. This lignin/chitosan composite represents a promising alternative to plastic.

Summary: We have developed a strategy to break down cellulose microfibrils in plant fiber cell walls. By impregnation, mild oxidation, and ultrasonication, we obtained molecularly-sized cellulose structures (cellulose ribbons) that maintain hydrophilic and hydrophobic properties. These cellulose ribbons exhibit excellent hydrophilicity and flexibility, allowing them to form gel-like Pickering emulsions suitable for direct ink writing at ultra-low solids content.

Summary: Cationic starch is commonly used as a paper strength additive in papermaking wet end applications. The study investigates the adsorption behaviors and strength enhancement of quaternized amylose (QAM) and amylopectin (QAP) on fiber surfaces. The results reveal that the adsorption layer thickness and structure of QAM and QAP are influenced by starch morphology, degree of substitution, pH, and ionic strength. Furthermore, the degree of substitution of QAM positively correlates with paper strength, while the degree of substitution of QAP negatively correlates with paper strength. These findings provide insights into the impact of starch morphology on performance and offer practical guidelines for starch selection.
