In this study, the functionalization of nanofibers by incorporating different particles and

additives into the polymeric matrix for developing ultraviolet protective materials was

investigated. Titanium dioxide was selected because of its known characteristic of

being a widely used material for obtaining ultraviolet protection. Besides, 1,3,7-

Trimethyl xanthine, which was used previously in medical applications to decrease

the harm of ultraviolet radiation on DNA, was used to see its potential in obtaining

ultraviolet protective nanofibers. By using these two different additives in different

concentrations, functionalized polyamide 6.6 nanofibers were produced, their ultraviolet

protection property and ratings were recorded, and the results were evaluated

comparatively. Addition of titanium dioxide in all concentrations significantly improved

ultraviolet protection of polyamide 6.6 nanofibers for both UVA- and UVB-type

radiations. Moreover, ultraviolet protection factor value of polyamide 6.6 nanofibers

was considerably enhanced by incorporation of 1,3,7-Trimethyl xanthine in the concentrations

of 15 and 20% w/w of the polymer; which of their protection ratings were

defined as ‘‘excellent protection’’ for both.
