Nano-silver/poly(2-acrylamido-2-methylpropanesulfonic acid (AMPS)-methyl methacrylate (MMA)) [P(AMPS-co-MMA)]composite materials were prepared with the silver nitrate solution containing AMPS and MMA monomers without initiator or reducer, in which Ag+ ion was reduced to nanosilver particles and the monomers were copolymerized by ultrasonic simultaneously. The microstructure of the nanocomposite materials was characterized by means of the transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR), UV-Vis and fluorescence spectrometer. The nanosilver particles were homogeneously dispersed in polymer matrix and the size of particles is in the range of 5 similar to 15 nm, the size and distribution of nano silver particles had something to do with ultrasonic time. Spectrum of FT-IR, UV-Vis and fluorescence were indicated that there is chemical action between namo-Ag and special group attached to the copolymer. X-ray photoelectron spectroscopy (XPS) was proved that the interaction between nano silver and the functional group attached to copolymer is of coordination. It is concluded that there is a kind of interaction phenomena of nanometal silver with effective polymer matrix in the nanocomposite materials.
