|Abstract:||Micro- and nanotechnologies are at the centre of numerous investigations and huge investments, essentially in the areas of information technologies and health care . The technologies utilised mainly take advantage of microelectronics and/or rather sophisticated “physical” techniques (laser ablation, PVD, ..).|
On the other hand, chemistry has anticipated for long the importance of decreasing the size in the search for new properties of materials, and of materials structured at the nanosize in a number of applications related to daily life.
Today, based on research initiated in the late 80s, we are mastering industrially the synthesis of particles in a range of sizes from 5 to 100s of nanometres and their functionalisation for adaptation to use in specific application media.
Coupling the skills in mineral synthesis, organic synthesis, physical-chemistry of complex media, and physics of materials, has been the key for the success of these developments.
Three main examples illustrating these achievements and will be presented :
- silicas for the reinforcement of mechanical properties of elastomers,
- cerium oxides as additives in the depollution of diesel engines,
- lamellar zirconium phosphates (alpha form) as reinforcing and gas-barrier agents in thermoplastics .
Some examples of other areas of application currently under development will also be illustrated.
