Abstract In this study, the functionality of polylactic acid (PLA) nanofibers was enhanced by blending polycaprolactone (PCL) and adding titanium dioxide nanoparticles. Various concentrations TiO 2 nanoparticles, ranging from 1 to 7% wt, were added PLA nanofibers. Optimal dispersion observed at 3% wt , resulting in 493.64 ± 129.78 nm fiber sizes. Blending with PCL a 1:1 ratio yielded fibers an average diameter 513.20 64.85 nm. The addition nanoparticles into PLA/PCL blends increased pore area due larger size. Mechanical testing indicated that strength slightly while ductility significantly. results for water uptake behavior showed NP improved absorption. Antibacterial activity evaluated against Staphylococcus aureus ( S.aureus ) Escherichia coli E.coli using agar disk diffusion method. NPs demonstrated inhibition zones 10.46 1.03 mm 19.30 1.47 13.33 1.15 21.71 1.74 respectively.

In this study, an improved PVA/PLA fibrous hemostatic membrane was prepared by electrospinning technology combined with air plasma modification. The treatment used to modify PLA enhance the interlayer bonding between PVA and membranes first, then improve capacity. surfaces of were oxidized after treatment, diameter reduced, roughness increased. Plasma enhanced interfacial bond strength PLA/PVA composite membrane, acted as a good mechanical support. Plasma-treated showed increasing liquid-enrichment capacity 350% shortened coagulation time 258 s. model liver that ability plasma-treated 79% compared untreated membranes, slight improvement over commercially available collagen. results fibers able achieve more effective hemostasis, which provides new strategy for improving performance materials.
