Fabrication and Characterization of Composite Nanofibrous Membranes With <scp>TiO₂</scp> Particles Against <scp>UV</scp> Radiation

ABSTRACT This study employs electrospinning to fabricate and characterize composite nanofibrous layers composed of polyamide 6 and titanium dioxide (TiO₂) particles. Polyamide 6 solutions were prepared with varying TiO₂ concentrations (5, 10, 15, 20, 30, 40, 50, 60, 70, and 80 wt%) to investigate the impact of filler content on the spinning process and the resulting nanofiber morphology. The conductivity and viscosity of these solutions were measured to assess their spinnability. The fabricated nanofibrous layers were characterized to determine the distribution of TiO₂ particles and their influence on the overall morphology. Additionally, the wetting behavior and ultraviolet radiation (UV) absorption properties of the layers were evaluated. The results indicate that nanofibrous layers containing 50% TiO₂ exhibit the highest UV absorption potential, making them promising candidates for further applications.
