Transparent conductive nanofibrous membranes have been successfully fabricated by sputter-coating a metal (Au, Pd, Pt, Ni, Ag, or Au/Pd alloy) onto a water-soluble-polymer nanofibrous template, followed by the dissolution of the template in a water bath. The size of the conductive nanofibers can be facilely controlled…

Abstract We studied peapods prepared with ferrocene (dicyclopentadienyl iron, Fe(Cp) 2 ) as filling species, which makes CNTs with diameters down to 1.1 nm accessible for filling. Two different single‐wall carbon nanotube (SWCNT) samples with mean diameters of 1.1 nm (HiPco) and 1.6 nm (DIPS) were used. Filling was do…
