Abstract

In the present work, we describe a “one-pot” route for the preparation of silver-PMMA nanocomposite. The formation of silver-PMMA nanocomposite takes into consideration the fact that free radical species are generated from the redox system containing AgNO3, H2O, and NaBH4. The methyl methacrylate (MMA) monomer is at first emulsified by OP-10 to form micelle. The mercaptoethanol plays an important role in the process of forming silver-PMMA shell-core structure. Polymerization of MMA takes place when the Ag+ is reduced to Ag. The free radical polymerization mechanism has been proposed according to the result of ESR analysis. The structure of the silver-PMMA nanocomposite has been characterized by FTIR, XRD, TEM, AFM, and DLS measurements.
