Abstract
Disclosed is a method of preparing polymer film-metal composites and uses of such composites. The metal can be in the form of a nanoparticle or a film. The methods comprise depositing on a surface, a composition comprising: a cationic metal precursor; a polymer film precursor that comprises a plurality of photopolymerizable groups; and a photoreducer-photoinitiator; then irradiating the composition under conditions to simultaneously reduce the cationic metal and polymerize the photopolymerizable groups to obtain the composite on the surface.
Claims20
A method for preparing a polymer film-metal composite, the method comprising:
- depositing on a surface, a composition comprising:
- a cationic metal precursor;
- a polymer film precursor that comprises a plurality of photopolymerizable groups;
- and
- a photoreducer-photoinitiator;
- and
- irradiating the composition under conditions to simultaneously reduce the cationic metal precursor and polymerize the photopolymerizable groups to obtain the polymer film-metal composite on the surface,
- wherein the polymer film-metal composite comprises metal nanoparticles embedded in the polymer film precursor,
- wherein the composition further comprises an agent that caps and/or stabilizes the nanoparticles, and
- wherein the polymer film precursor is obtained from a method comprising:
- reacting a monomer comprising two or more photopolymerizable groups with an anchor precursor comprising at least one metal-anchoring group and at least one group that will react with the photopolymerizable groups.
A polymer film-metal nanoparticle composite comprising a uniform distribution of metal nanoparticles embedded in a polymeric resin film, the polymeric resin film comprising a plurality of metal-anchoring groups, the metal-anchoring groups anchored to the nanoparticles, wherein the metal-anchoring groups are derived from dithiothreitol.
