This presentation will give an overview about Carbon Nanotubes (CNT) and CNT based wet coatings for transparent and electric conductive films. Since their discovery in 1991 by Ijima CNT are announced as on of the major material innovations of the last decades. CNTs offering a great number of potential applications such as, actuators, sensors, reinforced metals, ceramics and conductive composites. Within the last 10 years two major applications, touch screens and solar panel caused rising demand on transparent and conductive films (TCF). Nowadays most of such films and coatings are produces with sputtered ITO which have to major issues. ITO is limited resource and due to the rising demand the raw material price is continuously rising. Furthermore the sputtering process requires lots of energy and is quite expensive. Due to their high electrical conductivity and their nano scaled size, CNT's are supposed to replace ITO in some applications. Within this presentation information's about CNT's and their applications will be given. In the second section of the presentation the applications of transparent and conductive CNT coatings for PET and PC films will be discussed, as well as high conductive scratch resistant coatings on glass. In the last section a short Outlook of Graphene's potential impact on TCF will be given.
