Submitted Abstract

Design of nanocomposite coatings being composed of silicon-based organic-inorganic matrix and sensing molecules is an emerging scientific area. Even if significant progress on the development of such coatings was achieved by using mainly sol-gel processes in the past five years at laboratory scale, the use of an atmospheric pressure plasma for the elaboration of transparent sensing thin film (thickness below 500nm) is a new field or research. The influence of the deposition parameters on the growth mechanism, microstructure and the properties/performances of these coatings must be investigated to perform this kind of active surface. For example, the sensing molecule bonding and the repartition in silicon-based matrix as a function of parameters need more systematic research activities. The kinetic gas permeation of these transparent thin films and the control of this parameter according to the process parameters need more investigations and understanding. Also, deeper research on the sensing mechanisms and properties of these coatings remain to be studied both by using experiments and simulations. One interesting application to demonstrate the high potentialities of this smart material is food spoilage. Volatile amines produced during food deterioration, such as following bacterial growth in the presence of proteins, is one main envisioned application.The main objective of the SURFAMINE project is to achieve major advances in the understanding and the design of sensitive surfaces able to detect volatile organic compounds using a CVD-assisted atmospheric plasma to manufacture a sensing nanocomposite transparent thin film. The ability of this technique to promote this new surface functionality will be demonstrated in the case of the elaboration of organosilicone layer embedded with metalloporphyrin sensing molecules. For that, it is planned to implement on an atmospheric plasma reactor, an innovative high rate co-injection precursor system based on an ultrasonic atomizing nozzle. In parallel, new organo-metallic compounds (metalloporphyrins and dyes) will have to be synthesized to allow the multifunctional and smart properties. Within this study, we will also focus on the permeation of volatile amines into the plasma coatings and on the interaction between sensing molecules and volatile amines. To demonstrate the potentialities of this new active surface, food storage packages will be prepared and at the end of the project, experiments will be conducted to demonstrate the usefulness of such an amine sensing system in indicating food spoilage. To fulfil this ambitious objective, the SURFAMINE Consortium is constituted of different complementary research teams: the two research departments SAM and EVA from the CRP-Gabriel Lippmann (Luxembourg), the Johannes Gutenberg University of Mainz (Germany) and of Michigan (USA) and two industrial research centres, the Foil Innovation Centre (Luxembourg) and the Packaging Centre from ArcelorMittal Research (FranceBelgique). To launch the research associated, the SURFAMINE partners will divide the project into 4 main technical activities:Experimental development on the deposition of sensing plasma thin film and their surface characterizationsSynthesizing of new sensing molecules compatible with a plasma deposition process for volatile amine detectionExperimental study of the interaction of the sensing molecule with aminesFood storage/spoilage experiments
