Melamine foams, used as polymeric porous substrates, are first covered with a uniform coating of polydimethylsiloxane, thin enough to assure the preservation of their original porous structure. The polydimethylsiloxane layer allows the facile in-situ formation of metallic Au and Pd nanoparticles with sizes of tens of nanometers directly on the surface of the struts of the foam by the direct immersion of the foams into gold or palladium precursor solutions. The effect of the gold and palladium precursor concentration, as well as the reaction time with the foams, to the amount and sizes of the nanoparticles synthesized on the foams, was studied and the ideal conditions for an optimized functionalization were defined. Gold and palladium contents of about 1 wt.% were achieved, while the nanoparticles were proven to be stably adhered to the foam, avoiding potential risks related to their accidental release. application/pdf eng MDPI info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2020 The Authors Atribución 4.0 Internacional Metal nanoparticles Nanopartículas de metal Polymer foams Espumas poliméricas Polydimethylsiloxane Polidimetilsiloxano Melamine Foams Decorated with In-Situ Synthesized Gold and Palladium Nanoparticles info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.mdpi.com/2073-4360/12/4/934 SI
