contact with the pre formed gold electrodes optical dark field microscopy confirmed that the nanowire bundles were located at the bottom of the u02dc 5 10 u03bcm thick dried ctab films furthermore the nanowire films were deposited on a 1 cm 2 fused silica substrates also from 0 6 m ctab silver paint was applied in two parallel lines at the edges of the substrate and sheet resistances of the order of 100 u03c9 sq were measured after mild ethanol washing in particular the high flexibility of the film was demonstrated fig8 b where only up to 10 increase in the u02dc 100 u03c9 sq sheet resistance occurred for a film deposited on a pet substrate which was bended with a curvature radius of u02dc 1 5 cm upon relaxing the bend in the film the sheet resistance returned to its exact original value demonstrating the high flexibility of the nanowire film the films deposited on pet have shown the lowest resistivity results down to u02dc 60 u03c9 sq fig8 a 8c show visible light transmission curve of a nanowire film bending of pet substrate coated with a nano wire film and the periodic table as observed through the pet film.
