background

● Problems in flexible transparent conductive films (TCF)
・ITO has limited flexibility and abrasion resistance.
・PEDOT:PSS and Ag nanowire have insufficient durability.
・CNT-TCF have issues in performance and production process.

summary

● Simple fabrication via dispersing CNT in aqueous solution of PSS (Poly(p-styrene-sulfonic acid)) and coating
● Conductive (115 Ω/sq) and transparent (90%) Stable in air for >1000 h or at >250 C without passivation

predominance

● PSS is a promising dispersant and dopant for CNT
● No need for removal process of surfactant
    No need for additional doping process

application/development

● TCF for flexible & wearable devices
● Transparent heater for automobiles
● Rare metal-free TCF
