Abstract

The one-step process for synthesis of free-standing gold nanoparticle-polymer composite membrane obtained by reduction of chloroaurate ions by oxyethylene-linkage-bearing diamine at liquid-liquid interface was analyzed. A free-standing polyaniline-like polymeric material in which gold nanoparticles were uniformly dispersed was formed. It was observed that gold nanoparticle membrane was robust and could be generated in range of sizes and thicknesses with tailoring of porosity dependent on presence/removal of gold nanoparticles. The results show that gold nanoparticles have significant applications in separation methodologies.
