Advanced ultraviolet-light-absorption silk fabricated by decorating with TiO2 nano-particles

Ultraviolet radiation is always threatening our people's health, while the traditional clothes have not met the demands of resisting UV radiation. In this paper, we fabricated a new kind of silk coating with TiO2 nanoparticles. The obtained sample was characterized by SEM and XRD. Experimental UV spectra results show that this new kind of textile has an absorption peak at around 340nm with magnitude of over 65%. In this kind of textile, a majority of absorbed Ultraviolet radiation is contributed to the band-gap transition and surface Rayleigh scattering of the TiO2. The strong combination in the interlayer of TiO2 and silk is dependent on their electrostatic interaction. This silk can be utilized as the material of clothes and sunshades, even in the military application of stealth serve.
