Carbon nanotubes (CNTs) with high elastic, electrical, thermal and mechanical properties can be applied to flexible transparent conductive films instead of indium tin oxide (ITO) with inflexible property. However, the strong attraction force between the tubes produces the aggregation and the bundled forms. Therefore, a dispersion process for isolating CNTs is required. In this study, in order not only to disperse the CNTs in water but to coat the CNTs on PET film, we used mussel adhesive proteins (MAPs). MAPs have amphipathic property, so it could disperse CNTs in water. In addition, the CNTs which were cast through an ultrasonic spray could be stuck on PET film due to a strong adhesion property of the MAPs. Also, we tried to fabricate transparent conductive films with lower sheet resistance through heat treatment and vacuum ultraviolet (VUV) treatment. |
