摘要：

Surfaces of sulfate-terminated polystyrene microspheres are anisotropically modified with silver nanoparticles covering 20-50% of the sphere surface using electroless deposition. A PDMS templating method is employed. Silver nanoparticles are found to deposit uniformly onto the exposed sphere surfaces. The deposition is diffusion-controlled and the nanoparticles adhere strongly to the polystyrene particles despite extensive exposure to ultrasonication. Silver content is confirmed by EDAX analysis. The final silver coverage is controlled via the PDMS pre-curing conditions.
