A new era of electrically conductive coatings
Electrically conductive coatings are employed in a plethora of products from mobile phones and computers to medical, military and aerospace systems. Conventional coatings are very high in heavy metals and volatile organic compounds (VOCs), both of which are serious health hazards. Development of novel multifunctional polymer coatings with reduced environmental impact was an important objective of the EU-funded project TRANSCOND . Researchers went much further, though, with sprayable, transparent and permanently conductive coatings employing nano-structured carbon and boasting significantly enhanced technical properties. In just two short years, the partners have developed a range of commercially available coatings that can be obtained through links on the project website. In addition, three of the five products are compatible with the EU's directive on technical requirements for equipment used in potentially explosive environments (ATEX Directive 94/9/EC). The coatings are largely water-based for a major relief from VOCs. Depending on the application, they are compatible with glass, plastic and/or metal. One transparent coating is designed for displays, protective screens, oven doors and large areas such as flooring. In addition to traditional scientific dissemination routes, three project videos are available on the project website and on YouTube. A LinkedIn group has also been established. TRANSCOND's highly innovative electrically conductive coatings will help the small and medium-sized enterprises that have been integral in their development expand their markets considerably. The novel functionalities and enhanced properties will help them create new application potential as well, achieving an important increase in competitive position.
