Intrinsically conductive polymers - ICPs - offer many advantages compared to materials containing conductive inclusions such as metal or carbon. However, although ICPs are already well known ion laboratories, production on industrial scale is not yet possible because, among other things, the transformation process remains unknown. The aim of this project is the production of ICPs on a industrial scale for electromagnetic interference shielding (EMI).

The aims of the project are :
-Good synthesis of ICPs
-a better knowledge of the transformation process
-good knowledge and control of the physical properties of ICPs and their EMI shielding efficiency.
Polythiophene, polypyrrole and polyaniline routes have been studied. Polythiophene route had to be abandoned because of the low stability of such a conductive polymer. Polyaniline based conductive thermoplastic blends were synthesised and studied according to their rheological and electrical properties. Aging of such conductive materials was extensively studied in various degrading environments.

Polyaniline and polypyrrole based coatings were developed and polymer and latex synthesis were optimised. Polyaniline paints or thick coats of good electrical and mechanical quality have been achieved.

Demonstrators have been developed for each of the envisaged applications : cables, electrical boxes and acoustics.
Performances and aging of these demonstrators has been assessed by the industrial end-users involved in this research.
