Resumo(s): | In the current work, fibrous structures based on biodegradable polymer ε-caprolactone (PCL) functionalized with zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs) were produced by electrospinning, to achieve materials with ultraviolet (UV) protection properties. These nanofiber-based webs were produced either with ZnO or TiO2 NPs in different concentrations, as well with different densities, in order to study their influence in the UV protection properties. The webs were evaluated in terms of UV protection through the measurement of transmittance values with a spectrophotometer UV/Vis, followed by the calculation of the UVA transmission and ultraviolet protection factor (UPF) values. A set of nanofiber webs has shown UV protection capability, namely those with nanofibers functionalized with TiO2, that presented lower UVA transmission and higher UPF values. In opposition, the nanofibers produced without NPs, didn’t reveal UV protection properties, highlighting the potential of ZnO and TiO2 NPs in this field. |
