PATTERNING METHOD USING THIOSULFATE POLYMER AND METAL NANOPARTICLES

摘要

A thiosulfate polymer composition includes an electron-accepting photosensitizer component, either as a separate compound or as an attachment to the thiosulfate polymer. The thiosulfate polymer composition can be used in methods to form predetermined patterns of metal nanoparticles.

1. A method comprising:
providing a polymeric layer comprising a non-crosslinked thiosulfate polymer that also comprises pendant organic charged groups, photochemically reacting the non-crosslinked thiosulfate polymer to provide polymer layer areas comprising a crosslinked polymer having disulfide groups in the polymeric layer, optionally washing the polymeric layer to remove any non-crosslinked thiosulfate polymer while leaving the crosslinked polymer having disulfide groups in the polymeric layer, and contacting the polymeric layer with a dispersion of metal nanoparticles to complex the metal nanoparticles with the crosslinked polymer having disulfide groups.
