Abstract
A composition is provided that includes a polymer matrix. A core having a core surface is embedded within the polymer matrix. A polymeric ligand passivates the core surface and has a moiety Y, where Y is a Diels-Alder group of a diene or dienophile. A polymeric linker has a complementary Diels-Alder group diene or dienophile to moiety Y and forms a Diels-Alder bond with the moiety Y. A composition is also provided that includes polymer matrix having a matrix surface. A core having a core surface is present on the matrix surface. A polymeric ligand passivates the core surface and has a moiety Y, where Y is Diels-Alder group of a diene or dienophile. The polymer matrix and polymeric ligand together define a matrix-ligand Flory-Huggins binary interaction function greater than 0.
