Multiscale characterization of antimicrobial poly(vinyl butyral)/titania nanofibrous composites

Summary

This work demonstrates a fast, scalable route to antimicrobial composite nanofibre mats made by electrospinning poly(vinyl butyral) reinforced with titania (TiO₂). Titanium dioxide nanoparticles (about 3 wt%) and titania nanotubes (about 1 wt%) were dispersed in the polymer solution and spun into fibres using both single-needle and multi-needle systems, the latter enabling much higher production rates. The authors characterised how the processing setup influenced fibre morphology across several length scales, and evaluated the mechanical and antimicrobial performance of the resulting mats. The composites combined good mechanical properties with antimicrobial activity while being produced at high throughput, making them attractive for practical uses such as healthcare textiles, photocatalytic surfaces and protective fabrics.
