Nanocomposites based on metal and metal sulfide clusters ambedded in polystyrene.

Abstract

Transition-metal alkane-thiolates (i.e., organic salts with formula Me(SR)x,where R is a linear aliphatic hydrocarbon group, -CnH2n+1) undergo a thermolysis reactionat moderately low temperatures (close to 200 °C), which produces metal atoms or metalsulfide species and an organic by-product, disulfide (RSSR) or thioether (RSR) molecules,respectively. Alkane-thiolates are non-polar chemical compounds that dissolve inmost techno-polymers and the resulting solid solutions can be annealed to generatepolymer-embedded metal or metal sulfide clusters. Here, the preparation of silver and goldclusters embedded into amorphous polystyrene by thermolysis of a dodecyl-thiolateprecursor is described in detail. However, this chemical approach is quite universal and alarge variety of polymer-embedded metals or metal sulfides could be similarly prepared.
