In-Situ Formation of Ag Nanoparticles in Polystyrene (PS) Core-Polyacrylic Acid (PAA) Brush Particles by UV Irradiation

摘要

Nanoparticles consisting of noble metals have recently attracted much attention because such particles may exhibit properties differing strongly from the properties of the bulk metal [1]. Thus, such nanoparticles have interesting perspectives in the applications as catalysts [1-3], sensors [4], and electronics. However, the metallic nanoparticles must be stabilized in solution in order to prevent aggregation. Until now a lot of carrier systems have been reported to be used for the immobilization of metal nanoparticles, such as dendrimers [5-6], latex particles [7-8], microgels [9-10], or other polymers [11].
