ABSTRACT The poly(butylene adipate‐co‐terephthalate) (PBAT) nanofiber film prepared by electrospinning method exhibits limited application in many fields due to its poor flame retardancy and machinal property, despite being a biodegradable material with exceptional toughness ductility properties. In this work, we employed microfluidic technology continuously produce blue fluorescent carbon dots (CDs) on an aluminum‐based chip using citrate ethanolamine as precursors. Subsequently, utilizing technology, the CDs/PBAT composite films fluorescence were situ reaction. Interestingly, compared pure PBAT membranes, membranes exhibit tensile strength of 4.31 MPa, representing remarkable increase 3.24 times, elongation at break 491%, indicating improvement 1.62 times. More importantly, it had demonstrated that incorporation CDs into can achieve flame‐retardant effects. We firmly believe strategy could open up new idea for synthesis point out direction meaningful fabrication high property.

Abstract Soil microplastics (MPs) pollution has garnered considerable attention in recent years. The use of biodegradable plastics for mulching led to significant quantities plastic entering agro-ecosystems. However, the effects polylactic acid (PLA) on meadow soils remain underexplored. This study investigates impacts PLA varying particle sizes and concentrations soil physicochemical properties, enzyme activities, microbial communities through a 60-day incubation experiment. PLA-MPs increased pH, organic matter (SOM), total nitrogen (TN) available potassium (AK) content, as well enhanced activities superoxide dismutase (S-SOD), peroxidase (S-POD), catalase (S-CAT), β-glucosidase(S-β-GC) urease (S-UE) activities. Conversely, decrease alkaline phosphatase (S-ALP) activity was observed. influence properties more pronounced with larger sizes, whereas smaller particles had greater effect Additionally, an increase abundance Acidobacteriota, Chloroflexi, Gemmatimonadota, while Proteobacteria, Actinobacteriota, Patescibacteria declined. Mental test analysis indicated that AK, S-UE, S-β-GC are primary factors influencing community composition. Phylogenetic Investigation Communities by Reconstruction Unobserved States (PICRUSt2) demonstrated modify bacterial metabolic pathways. Our results suggest size concentration differentially affect nutrients structure function, observed at higher concentrations.
