Résumé

A new, facile in-situ method for synthesis of polymeric nanocomposites (NCs) with nanoparticles (NPs) of Au, Pt and Pd is proposed. The method involves reduction-coupled sorption of Au(III), Pt(VI), and Pd(II), which avoids diffusion limitations, allowing the precipitation and stabilization of the NPs directly in the polymeric matrix. The obtained nanomaterials were characterized by transmission electron microscopy (TEM), and Fourier-transformation infrared spectroscopy (FT-IR). NPs loaded into polymers were also investigated using X-ray diffraction (XRD). Based on the results, it was concluded that the amino functionalities simultaneously reduced noble metals ions and capped the NPs. The average diameter of the obtained AuNPs ranged from 25 to 109 nm, while reduction-coupled sorption was carried out in 1 and 3 mol L
