Abstract:
The present disclosure provides an encapsulated particle for anti-UV radiation. The encapsulated particle includes a core comprising an anti-UV agent, and a shell at least partially enclosing the core and comprising a polymer. Due to the presence of the shell, the anti-UV agent can be released into surroundings at a controlled manner. The encapsulated particle can be incorporated into coatings or articles to extend their service life.
