Research progress on UV shielding of polydopamine and its application
The anti-UV mechanism of polydopamine(PDA)is described from the aspects of chemical structure,physical properties and biological protection,and the methods of preparing nanoparticles,mussel capsules and surface coatings based on dopamine self-polymerization are summarized.The application scenes of PDA anti-UV substrates are classified according to anti-UV film,coating,gel and sunscreen,which provides a reference for further exploring the anti-UV mechanism of PDA and expanding the appli-cation of PDA composites.
