Electrospun Polymeric Composite Fibers Containing Te-Doped Bioactive Glass Powders

Summary

This study prepares composite fibres in which poly(ε-caprolactone) carries bioactive glass powders doped with tellurium, a filler chosen for its combination of bioactivity, antibacterial action and antioxidant behaviour. Acetic acid served as the solvent for the polymer matrix, and FESEM confirmed that glass powders were well incorporated into the fibres at loadings up to 20% by weight. Wettability, mechanical behaviour, in vitro stability and preliminary antibacterial performance were then assessed: treatment in acetic acid left the bioactivity of the glass intact, while the tellurium-doped powders improved the wettability of the PCL matrix - a promising combination for bone contact and infection-resistant scaffolds.
