The films of single-walled carbon nanotubes (SWCNTs) are a promising material for flexible transparent electrodes, which performance depends not only on the properties individual but also, foremost, bundling nanotubes. This work investigates impact densification optical and electronic SWCNT bundles fabricated films. Our ab initio analysis shows that optimally densified bundles, consisting mixture quasi-metallic semiconducting SWCNTs, demonstrate behavior can be considered as an effective conducting medium. density functional theory calculations indicate band curving bandgap narrowing with reduction distance between inside bundles. Simulation results consistent observed conductivity improvement shift absorption peaks in isopropyl alcohol. Therefore, also should building blocks high-performance conductive SWCNT-based
