Roll-to-Roll Manufacturing of Transparent Conductive CNB Films

Canatu has developed a unique Direct Dry Printing® (DDP) process for Roll-to-Roll manufacturing of carbon nanomaterial thin films. DDP is a one-step process combining floating-catalyst CVD synthesis of carbon nanomaterials and direct printing of thin films from the resulting carbon nanomaterial aerosol flow. In this work, DDP has been applied to produce high-purity Carbon NanoBud® coatings on plastic substrates (CNB film). Canatu is now increasing the level of automation using modular equipment structure allowing for flexible capacity increase. Key features of the transparent conductive CNB films are reviewed, and some of the key applications of the CNB films in free-form 3D shaped touch sensors are presented.
