Synthesis of Ag-coated polystyrene colloids by an improved surface seeding and shell growth technique

Preparation and characterization of silver-modified poly(vinyl alcohol)/polyethyleneimine hybrids as a chemical and biological protective material

“…The particle size of Ag in the Polymer/Ag (21 nm) is smaller than that in the BC/Ag (200 nm) [23]. This method may be extended to other systems, such as poly(ethylene oxide), poly(vinyl alcohol) and other watersoluble polymers, and it is especially suitable to the preparation of polymer/oxide nanohybrids [2,8,14,18].…”

“…PEI can act as a chemical barrier because it contains primary and secondary amino groups which can react with sulfur mustard and soman. Due to the multi-functional characteristic of PEI, Ag seeds formed in-situ [18] and were immobilized in the PVA/PEI blend. It is expected that the entanglement of the polymeric carrier with PVA chains and the small pore size of PVA lead to the retainment of carrier in the membrane.…”

Features of the stabilization of silver nanoparticles by carbonyl-containing polymers

“…Among stabilizers of polymeric type polyacrylic (PAA) and polymethacrylic (PMA) acids and their salts [13,14], polyacrylamide (PAAm) and its derivatives [15,16], polyalkyl(meth)acrylates [17,18], polyacrylonitrile (PAN) [19][20][21], polyamido acids (PAmA) [10], poly(N-vinyl-2-pyrrolidone) (PVP) [22][23][24], polyamides [25], polyamidoamines [26,27], polyurethanes (PU) [28], polyethyleneimine [29,30], polyaniline [31,32], poly(4-vinylpyridine) [33], polyvinyl alcohol (PVA) [34,35], polysaccharides [36,37], polyethers [38,39], polypeptides [40,41], polyether sulfones [42,43], and certain others have proved notably effective.…”

Controllable synthesis and catalysis application of hierarchical PS/Au core–shell nanocomposites

“…The traditional self-assembly synthesis routes are based on a two-step process, synthesis of Au colloids, and immobilization on supports via electrostatic effect, covalent interaction, or ligand coordination [26][27][28]. In these methods, a necessary step is to modify the cores with the surface functional groups, such as -NH 2 , -SH, positive charges and polyelectrolytes [29][30][31][32][33], which are effective for the connection of small Au NPs. For instance, Jiang et al used ''treeshape'' surfactant bis(amidoethyl-carbamoylethyl) octadecylamine (C18N3) as the glue for the fast combination of Au NPs by selfassembly and subsequently prepared gold shell via seed-growing method [34].…”
