Resumen:
Visible light exposure of films containing silver nanoparticles (AgNPs) shows that the enhanced field around AgNPs in a thin film containing an azo free radical initiator(AIBN) and a triacrylate selectively cross-links the triacrylate within the plasmonic region around the particles. The crosslinked polymer is less soluble than its precursor and behaves as a solubility switch. After the film is developed with ethanol, polymer-encapsulated nanoparticles are preserved on the surface.The 8-10 nm polymer structure that encapsulates theparticles effectively maps and preserves the morphology of the plasmon field in AgNP-controlled nanostructures.
