Electrochemical formation and properties of polymethylolacrylamide film with inclusion of platinum particles

Electrochemical one-step synthesis of hybrid nanocomposites Au/polymer

“…It follow from [18,19] chitosan and AuCl 4 -are formed a complex. Authors [20] found that the UV initiated synthesis of gold nanoparticles in the chitosan presence, which simultaneously performs stabilizing and restoring functions, results in the formation of larger gold nanoparticles.…”

“…4 1 mmol/l --+ + a Zinc chloride is an indirect initiator of the polymerization of acrylamide [16,17].…”

“…The following substances were used for the formation of metal-polymer composites: Acrylamide (AA) 2 crystallized (Paneco), Formaldehyde (F) GOST 1625-89 (Neva Reactive), N, N'-methylene-bisacrylamide (MBAA) 98% (Paneco), Zinc chloride 97-100.5% Extra Pure (Scharlau), HAuCl 4 •4H 2 O (Voikov plant), chitosan hydrochloride (Cht) (Russia), hydrochloric acid (Neva Reactive).…”

“…However, our studies have shown that nanoparticles of a noble metal can also be introduced into a non-conductive polymer matrix. So, it was shown [4] that the electropolymerization composition developed by us on the basis of acrylamide and formaldehyde makes it possible to obtain a polymethylolacrylamide film/Pt. It was found that carrying out electropolymerization in a monomer composition with the addition of H 2 PtCl 6 leads to the simultaneous occurrence of several processes: the formation of a polymer matrix, the electro reduction of PtCl 6 2-ions to Pt 0 , and the introduction of platinum nanoparticles into the volume of the polymer film.…”

“…The incorporation of polymers with other materials can produce new hybrids with distinct properties that are not observed in the individual components. Usually, conductive polymers (polyaniline, polypyrrole, polythiophene and their derivatives [3]) or nonconductive polymers (polymethylolacrylamide [4]) are used as polymer matrix. Noble metal nanoparticles (Au, Ag, Pt and Pd) [3][4][5][6][7], graphene [6] and metal oxides (SnO 2 , Fe 3 O 4 ) [8,9] can be used as inorganic fillers.…”
