Flexible Transparent Conductor Film using Graphene-Carbon Nanotubes on PDMS
Conventional transparent conductive films (TCF) used indium tin oxide (ITO) as the conductive material but the issues with film brittleness, low infrared transmittance, scarcity of indium, and high-cost of the preparation procedure limits the mass production of flexible TCF.

| Summary: | Conventional transparent conductive films (TCF) used indium tin oxide (ITO) as the conductive material but the issues with film brittleness, low infrared transmittance, scarcity of indium, and high-cost of the preparation procedure limits the mass production of flexible TCF. Carbon nanotube (CNT) and graphene are two promising alternatives to replace ITO-based TCF due to its high electrical conductivity, excellent mechanical strength, flexibility and transparency, and optical properties. Graphene and graphene-CNT was grown using the CVD method and characterized using the Raman spectroscopy, Hall Effect measurement system, the UV-vis spectrophotometer and the four point probe method to study the mobility, resistivity and optical properties of graphene and graphene-CNT on polydimethylsiloxane (PDMS) substrate. The average mobility obtained for graphene and graphene-CNT are 1633.76 cm2/Vs and 3445.74 cm2/Vs respectively. |
