Summary
The main objective of the project is to achieve major advances in the understanding, design and manufacturing of nanocomposite thin films able to detect volatile organic compounds. The sensitive surfaces, composed of metalloporphyrins sensing molecules embedded in an organosilicone matrix, will be elaborated by an atmospheric pressure plasma-assisted CVD.
To fulfill this ambitious objective, the SURFAMINE Consortium is constituted of different complementary research teams: two research departments, SAM and EVA, from the CRP-Gabriel Lippmann (Luxembourg), the Johannes Gutenberg University of Mainz (Germany) and two industrial research centres, the Foil Innovation Centre (Luxembourg) and the Packaging Centre from ArcelorMittal Research (France). To launch the research associated, the SURFAMINE partners will divide the project into 4 main technical activities (WP). The first task will focus on the experimental development of a new atmospheric plasma process for the elaboration of nanocomposite smart coatings. The SAM department from the CRP-GL will set-up a codeposition device working with one mixed liquid source (metalloporphyrin molecules & organosilicone precursor) injected together from an atomizing system into the plasma discharge or post-discharge. To optimize the nanocomposite plasma films, chemical and physical surface characterisations will be done with the different analytical techniques available in the SAM department.
The Institute of Inorganic Chemistry of Johannes Gutenberg University of Mainz will synthesise new sensing molecules compatible with a plasma deposition process for volatile amine detection. New sensing molecules for volatile amine detection will be designed and synthesized in order to be compatible with atmospheric-pressure plasma deposition and to promote a selective detection of volatile amine molecules. In parallel, simulation works at the molecular level in view of predicting the interaction between sensing molecules and amine molecules will be developed. The third WP, lead by the EVA department of the CRP-GL, will deal with the experimental study of the interaction of the sensing molecule with amines The objective is to obtain a good idea on the detection of various volatile amines, with metalloporphyrin molecules alone or embedded in a plasma thin film.
This will include detection range, threshold of detection, and concentration level to get a color change visible by the human eye. In addition, it will be evaluated whether variable conditions of the environment such as different temperature, CO2 content or humidity, or age of the film do impact these parameters. To demonstrate the potentialities of this new active surface, food storage packages will be prepared by the Foil Innovation Center of Novelis. The aim of this last WP is to conduct simulated food storage conditions with protein rich foods likely to undergo spoilage in releasing volatile amines, and in evaluating the correlation between biogenic amine formation, volatile amine formation, and colour change observed with the metalloporphyrin dye. Varying conditions as applicable for real food storing will be included.
