High-performance CNT/Sol-Gel electrodes

A penetration based method, forming highly conductive CNT/Sol-Gel composite films, is reported herein. These Coatings are suitable for a wide range of applications like electromagnetic shielding, optical devices or high thermal stable composite electrodes. The presented method is unconventional but very suitable for composite film preparation. To our knowledge it is used for the first time. Unlike standard methods where at least two components, in this case CNTs and Sol-Gel material, were homogenously mixed with each other, this new approach uses a penetration effect forming the composite film. This method also allows a detailed study of the electrical influence from the Sol-Gel on CNT networks during different phases of process steps like drying and sintering temperatures.
