Times Cited Count:1 Percentile:10.71(Chemistry, Physical)Polyvinylpyrrolidone (PVP)-Pt nanoparticles (NPs) hybrid nanowires were fabricated by high energy ion beam irradiation to PVP thin films including HPtCl. Single ion hitting caused crosslinking reactions of PVP and reduction of Pt ions within local cylindrical area along an ion trajectory (ion track); therefore, the PVP nanowires including Pt NPs were formed and isolated on Si substrate after wet-development procedure. The number of Pt NPs was easily controlled by the mixed ratio of PVP and HPtCl. However, increasing the amount of HPtCl led to decreasing the radial size and separation of the hybrid nanowires during the wet-development. Additional electron beam irradiation after ion beam improved separation of the nanowires and controlled radial sizes due to an increase in the density of crosslinking points inner the nanowires.

A basic extractant Aliquat 336 dissolved in a mixture of ethanol and NaOH aqueous solution was impregnated to carboxydecanyl-thiol (CDT) group containing polymer chains grafted onto a porous sheet. The CDT group was introduced into the graft chain by a reaction of the epoxy group of poly-glycidyl methacrylate (GMA) chain grafted onto the porous sheet with 11-mercaptoundecanoic acid. The electrostatic interaction between the carboxyl moiety of the CDT group and the quaternary ammonium group of Aliquat 336 gave rise to a high-density impregnation of Aliquat 336. Palladium chloride (50 mg-Pd/L) in 1 M HCl was forced to permeate through the pores of the Aliquat 336-impregnated porous sheet. The binding efficiency, defined as the ratio of number of moles of palladium adsorbed to half the number of moles of impregnated Aliquat 336, was found to be 64%.
