In-Situ Silver Nanoparticle Formation on Surface-Modified Polyetherimide Films

This paper extends the scope of a novel process previously reported by the group for the hydrolysis and subsequent metallization of polyimide substrates to encompass polyetherimide. Silver nanoparticles are grown in-situ by chemical reduction of silver ions implanted in the substrate. Factors affecting the level of hydrolysis are investigated, with temperature of the hydrolyzing solution found to be the key factor. The presence of silver nanoparticles is also confirmed by X-ray diffraction.
