An Organic/Inorganic Nanocomposite Consisting of Polymuconate and Silver Nanoparticles

Abstract

Summary: We have fabricated a nanocomposite consisting of a crystalline polymer and fine metal particles. The intercalation of alkali metal ions into the layered polymer crystals, which were prepared by the solid state polymerization of dodecylammonium muconate, was achieved by heterogeneously stirring the reacting solid polymers in a solution of sodium hydroxide in methanol at room temperature. An ion exchange reaction was similarly carried out in a silver nitrate solution, which was followed by photoreduction, leading to the formation of fine silver particles in the crystalline polymer (the organic matrix). By controlling the amount of silver ions introduced, we have fabricated an organic/inorganic nanocomposite containing silver nanoparticles with well controlled size and distribution, the characteristics of which were measured by transmission electron microphotography, UV‐visible diffuse reflectance spectroscopy and a small‐angle X‐ray scattering method. magnified image

Silver nanoparticle deposition on hydrophilic multilayer film surface and its effect on antimicrobial activity

“…The synthesis of silver nanoparticles, with an average particle size of $ 8 nm homogeneously dispersed in PVP, has been achieved by the polyol reduction of silver nitrate with ethylene glycol (EG), using a sonochemical process. 21 Different methods have been used to produce polymer-silver nanoparticles composites, including; in situ polymerization, 22 sol-gel synthesis, 23 solidstate polymer transformation, 24 cosputtering silver nanoparticles into a polymer, 25 magnetron sputter coating of polymer with nanosilver, 26 and so forth. The sonochemical method enables the synthesis of nanoparticles and their deposition on various substrates in a one-step procedure.…”

Synthesis of Silver Nanoparticles Templated by TEMPO-Mediated Oxidized Bacterial Cellulose Nanofibers

“…Carboxylate groups along the entire nanofiber surface can be used as host compounds to quantitatively introduce guest metal ions by an ion-exchange reaction, which should bring about salt formation with the regular arrangement. , After the ion-exchange process, a reduction reaction of metal salt on the nanofiber surface can lead to fine metal particles. We have demonstrated herein a facile fabrication of silver nanoparticles on the surface of TEMPO-oxidized BC nanofibers, which serve as efficient templates to support metal nanoparticles.…”

Laccase/TEMPO-mediated bacterial cellulose functionalization: production of paper-silver nanoparticles composite with antimicrobial activity

“…Once the cellulose is oxidized and new functional groups are created, compounds can be added in order to provide new functionalities or to generate new composites (Johnson et al 2011). Carboxyl groups have been used as host groups to introduce metal ions by an ionexchange reaction Matsumoto et al 2006;). Metal nanoparticles have been proposed in different catalytic, photoelectric, magnetic, sensor, and biomedical applications due to their electronic, optical, and chemical properties ( Zhou et al 2003;Sondi et al 2004;Jun et al 2007;Wu et al 2008).…”
