The disclosure relates to encapsulated UV (ultraviolet) stabilizer/absorber nanoparticles, which nanoparticles limit or prevent the migration of UV stabilizers/absorbers to the surface of a coating in service and/or which otherwise preserve the UV-resistance properties of the UV stabilizer for a longer period once incorporated into a UV-protective coating. The nanoparticles each include a clay or other nanotube encapsulating body such as a halloysite nanotube (HNT) and a UV stabilizing material within the interior cylindrical volume of the nanotube encapsulating body. The UV stabilizing/absorbing material can include one or more of lignin, a biomass extractive, a phenolic biomass material, and an organic UV stabilizer. The encapsulated UV stabilizer nanoparticles can be incorporated into a polymer composite as a heterogeneous phase distributed throughout a continuous polymer matrix. The polymer composite can be applied as a coating or film to an underlying substrate to form a corresponding coated article.

A method of forming a composite material includes photo-initiating a polymerization of a monomer in a pattern of interconnected units to form a polymer microlattice. Unpolymerized monomer is removed from the polymer microlattice. The polymer microlattice is coated with a metal. The metal-coated polymer microlattice is dispersed in a polymer matrix.
