Highly conductive paper fabricated with multiwalled carbon nanotubes and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) by unidirectional drying

摘要: Poly(3, 4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) was used to directly disperse multiwalled carbon nanotubes (MWNTs) into a stable solution without the aid of any other surfactants. The coated onto paper substrates and subsequently dried via two different methods: conventional multidirectional drying special unidirectional method with ceramic heating board. samples that were using had lower resistance than when method, which allowed it have better conductivity. For solutions containing 1–4 mg/mL MWNTs, dispersed 1 PEDOT:PSS, measured conductivity ranged from 21 ± 0.5 46 10 S/cm. These values are one three orders magnitude higher those obtained for MWNT films often reported in literature as well we fabricated MWNTs SDBS, or PEDOT:PSS by itself. AFM SEM images showed surface made surfactant very smooth layers tended be thinner It demonstrated FTIR analysis become part 3D structure substrate material because chemical bonding between fibers occurred during stage.
