Imprinting of metal receptors into multilayer polyelectrolyte films: fabrication and applications in marine antifouling.

ABSTRACT: Polymeric films constructed using the layer-by-layer (LbL) fabrication process were employed as a platform for metal ion immobilization and applied as a marine antifouling coating. The novel Cu²⁺ ion imprinting process described is based on the use of metal ion templates and LbL multilayer covalent cross-linking. Custom synthesized, peptide mimicking polycations composed of histidine grafted poly(allylamine) (PAH) to bind metal ions, and methyl ester containing polyanions for convenient cross-linking were used in the fabrication process. Two methods of LbL film formation have been investigated using alternate polyelectrolyte deposition namely non-imprinted LbL_A, and imprinted LbL_B. Both LbL films were cross linked at mild temperature to yield covalent bridg
