More Information
Summary:The present disclosure provides an article. In an embodiment, the article includes a substrate and a coating on the substrate. The coating includes a composition. The composition includes a plurality of nanoparticles, each nanoparticle having a ligand linked to a surface of each nanoparticle. The composition includes a plurality of block copolymers. Each block copolymer includes a linking block and a nonlinking block. The linking block is a random copolymer composed of at least two different monomers. At least one of the monomers is a linking comonomer. The linking comonomer is directly linked to the ligand to form a first microdomain consisting of the linking block, the nanoparticles, and the ligand. The composition further includes a second microdomain consisting of the nonlinking block.
