Specular transmittance at λ=550 nm as a function of sheet resistance for (a) AgNW@nanopapers prepared by filtration coating, bar coating and spin coating, and AgNW@PET films prepared by drop coating, bar coating and spin coating, (b) CNT@nanopaper prepared by filtration coating and CNT@PET film prepared by drop coating. In each case, transmittance values were evaluated with the substrate as a reference. AgNW, silver nanowire; CNT, carbon nanotube; PET, polyethylene terephthalate.
