Project Name:

Smart Inks as a Standard Testing Tool for Self Cleaning Surfaces (INTEC)

The INTEC project is medium-sized collaborative research a Coordination and Support Action funded by the European Union's Seventh Framework Programme for Research (FP7) - "Cooperation", Theme 4: Nanosciences, Nanotechnologies, Materials and New Production Technologies - NMP, topic Support for Standardisation Needs - Coordination Actions (FP7-NMP-2012-CSA-6).

The INTEC project was supported by a consortium of members both from industry and academia. The successful accomplishing of all the task is owing to an intensive communication and collaboration of all the INTEC participants.

The INTEC project has developed a novel methodology for evaluation of and comparison of photocatalytically active, also known as self-cleaning, surfaces. This method is described in two drafted standards and those are now both officially accepted as a CEN (the European Committee for Standardization) PWI (preliminary working items) documents.

The self-cleaning surfaces are now developed for most building materials. The main benefits of this recent technology is that such surface retains its appearance for longer and more importantly also this market is growing yet it lacks a rapid and visual test and standard, this is particularly important in case of these materials as the self-cleaning surface is invisible to human eye. All the standards that are in use to-date are lab based, requiring a trained personnel as well as expensive instrumentations and in most cases takes over 24 hours to complete. The work involved in this project was based on recently published (by one of the INTEC partner) articles where a smart ink technology is used to reveal a presence of a self-cleaning material is described. This photocatalyst activity indicator inks are applied on the surface as a film that changes its colour with a rate proportional to the photocatalytic activity of the self-cleaning, photocatalytically active material under the test ( ). It is important to state that this method is not to replace but rather complement to the standards and tests that are available now and therefore help to strengthen and help the growing industry.

The main activities of the INTEC project have been:

  1. Preparation and testing different photocatalyst activity indicator inks for a range of self-cleaning surfaces.
  2. Preparation and distribution of typical self-cleaning materials samples based on glass, tiles, paint, concrete and fabrics for round robin tests.
  3. Conduction of a series (eight in total) of round robin tests to identify the best ink and protocol for each very different self-cleaning surface.
  4. Engagement with and presentation of the achieved work to relevant CEN committee (TC386) and using feedback to improve on the prepared draft standard.
  5. Prepare a CEN standard for photocatalyst activity-measuring inks accepted by CEN/TC386.
  6. Dissemination of the work, mainly through two workshops that were organised for relevant public throughout the project.
