The results indicated that the nanocomposites exhibited much less degree of ageing degradation, due to a strong UV shielding ability of the nano-TiO2. Particularly, the polyester/nano-TiO2 presented an improvement of 42.5% in the gloss retention and a reduction of 27.6% in the colour aberration after 1500 h UV ageing. This work proposed a dry modification method for the nano-TiO2 and its application Selleck Napabucasin as functional nanoscale additive, which are highly available for the widespread applications of polyester resin/TiO2 composites, and would provide considerable insights into the protection of natural and synthetic carbohydrate polymers from the UV irradiation.
