Combinatorial Polymer Library Approach for the Synthesis of Silver Nanoplates

Abstract

We employ a combinatorial library approach to control the shape of the silver nanostructures by regulating the structure of their seeds. Twenty-four polymers are investigated in detail with respect to their functionalities, chemical structures, molecular weights, and charges, each of which turns out to play significant roles in synthesizing high-quality silver nanoplates at room temperature in a fast manner. A mechanism depicting the exceptionally stable seed structures ‘stitched’ by polymer threads is proposed, which clearly explains the experimental observations.

Durable Antimicrobial Behaviour from Silver-Graphene Coated Medical Textile Composites

“…The experimental UV-Vis data for synthesized plasmonic hybrid nanostructured samples demonstrates a well-separated single absorption peak in all cases, which corresponds to the surface plasmon resonance (SPR) of spherical AgNP, as encapsulated within the polyviscose fabric substrate (Figure 3) [109]. Surface plasmons are the in-phase oscillations of free electrons at the interface of a metal and dielectric, as indicated by a strong absorption at the resonance wavelength in a UV-Visible absorption spectrum [110][111][112][113][114][115][116][117]. The SPR band position depends on parameters such as size, shape, and polydispersity of nanostructures, even though it is the ability of rGO to otherwise enhance and control the loading and embedding of AgNPs, due to improved specific surface areas thought to be the reason for the divergence in the signal between the Ag and Ag-rGO samples [56].…”

Wet-chemical synthesis of two-dimensional metal nanomaterials for electrocatalysis

“…Organic ligands, e.g. organic amines [ 27–32 ], halogenic-organic ligands [ 23 , 33–36 ] and polymeric ligands [ 37–41 ], have been widely used to synthesize 2D metal nanomaterials, and can not only lower the surface energy of their specific facets, but also stabilize their 2D structure [ 15 ]. For instance, our group first synthesized 4H-phase Au nanoribbons with a thickness of 2–6 nm using oleylamine and 1,2-dichloropropane as organic ligands in the presence of hexane.…”

Thin metal nanostructures: synthesis, properties and applications

“…47 Recently, a very detailed study of the polymerassisted synthesis of Ag nanoplates suggests that the physical properties of polymers including length, amphiphilic structure, charge and the types of polymer chains, have signicantly affected the synthesis of metal nanostructures. 93 Nonionic surfactants, such as OA and OAM, have also been used for the synthesis of metal nanoplates and nanosheets in the oil phase at a relatively high temperature. In 2001, Alivisatos et al rstly reported the synthesis of hcp Co nanodisks with a thickness of $4 nm from Co 2 (CO) 8 with a combination of OA and TOPO in o-dichlorobenzene at about 200 C. 32 They found that the growth rate of different crystal facets can be regulated by changing the composition of the OA and TOPO mixed surfactant.…”
