Summary: Petroleum-based polymers are harmful to the environment due to their non-biodegradability. Researchers have been working on developing ecological packaging materials from natural resources like polysaccharides and proteins. However, films and coatings made from natural biopolymers have inferior properties compared to synthetic polymers. Plant extracts have been found to alter the properties of biopolymers and can be used for biodegradable food packaging. They increase thickness, reduce transparency and water vapor permeability, and have negative effects on mechanical properties and biodegradation rate.

Summary: A series of SiO2 coated TiO2 particles (TiO2@SiO2) were prepared as UV-shielding fillers for UV-curable coatings. The presence of a continuous and dense SiO2 layer on TiO2 surface not only improved the dispersibility of TiO2, but also effectively inhibited the photocatalytic activity of TiO2 without sacrificing its UV-shielding ability, thereby significantly enhancing the anti-aging property of UV-curable coatings. Salt spray test showed that the aged UV-cured coating with TiO2@SiO2 exhibited better corrosion protection behavior than the aged pure resin coating as well as the aged TiO2 coating.
