Patent ID: 7875416

Claim:
A method of preparing a photosensitive polymer complex containing silver nanoparticles, comprising: applying a composition including a multifunctional epoxy resin, a photoacid generator, an organic solvent, and a silver compound on a surface of a substrate to form a film; photoreducing the silver compound by selectively exposing the film to light using a photomask having a pattern, and thereby forming silver nanoparticles uniformly dispersed in the photosensitive polymer complex; and developing the exposed film using a developing solution, wherein the silver compound is at least one selected from a group consisting of silver acetate, silver tetrafluoroborate, silver thiocyanate, silver trifluoromethanesulfonate, silver sulfate, silver phosphate, silver trifluoroacetate, silver oxide (I), silver oxide (II), silver iodide, silver chloride, silver carbonate, silver hexafluorophosphate, silver fluoride, silver bromide, and silver hexafluoroantimonate.
