Researchers at KAUST have developed highly transparent and conductive graphene oxide-single-walled carbon nanotube (SWCNT) hybrid films using a simple and scalable Langmuir-Blodgett assembly technique. The films exhibit excellent optoelectronic properties, making them promising materials for various applications in electronics, optoelectronics, and electrochemical devices.
The research team, led by Dr. Biao Zhang, a postdoctoral researcher in the Computer Science department at KAUST, used a layer-by-layer assembly approach to fabricate the hybrid films. Graphene oxide sheets and SWCNTs were alternately deposited onto a substrate, forming a highly ordered and uniform film. The resulting films exhibited high transparency (over 90%), low electrical resistivity (less than 100 ohms per square), and excellent mechanical stability.
The researchers believe that the unique properties of the hybrid films are attributed to the synergistic effects between graphene oxide and SWCNTs. Graphene oxide provides high transparency and mechanical strength, while SWCNTs contribute to electrical conductivity. The combination of these two materials results in a material with superior properties compared to either material alone.
The hybrid films have potential applications in a wide range of devices, including transparent electrodes, solar cells, and sensors. The researchers are currently exploring the use of the films in flexible and wearable electronics.
The research was published in the journal ACS Applied Materials & Interfaces. The research team included Dr. Zhang, Dr. Benjamin Haddow, and Professor Andrew Birch from KAUST.
