Research activities
Nos activités de recherches s’organisent au sein et à l’interface du développement de 4 thématiques de recherche. Ces matériaux, leur étude et leurs combinaisons peuvent trouver des applications dans 3 principaux domaines :
4 THEMATICS
3 FIELDS OF APPLICATION
Most of the materials developed at the LPPI are designed and conceived to offer innovative solutions, or even technological breakthroughs, for a variety of applications. The laboratory's strategy is generally organised as follows:
- Synthesis of materials, ranging from small molecules to polymers. The geometries of the materials include (i) ‘1D’ structures (functionalization of textile yarns, whether conductive or not, by electronically and/or ionically conductive polymers), (ii) “2D” materials (functionalization of surfaces, monomolecular films, thin films or membranes), (iii) ‘3D’ micro, meso or macroporous materials and even (iv) 4D materials combining a three-dimensional structure and an electromechanically stimulable character
- Physico-chemical characterisation of these materials. Taking into account the problems associated with the presence of interfaces resulting from combinations of materials that are immiscible or immiscible, as well as understanding the ageing mechanisms of the materials studied, are cross-cutting aspects of all our activities. Similarly, electrochemical modelling and characterisation are tools that are almost systematically used when an electrical charge conducting system (ionic or electronic) is present in the material.

Combining these materials and integrating them, where appropriate, into functional devices or even demonstrators to enable their evaluation, which may lead to a return to the synthesis, if necessary.
