PHOTOCHEMICAL MODIFICATION OF SOLID MATERIALS

The present invention relates to a process for modifying or functionalizing oxide surfaces, such as surfaces of SiO2 and A12O3, but also metals including alloys such as stainless steel with alkenes or alkynes under mild conditions by photochemical reaction. The process is very well suited to form pa...

Beschreibung
Zusammenfassung:	The present invention relates to a process for modifying or functionalizing oxide surfaces, such as surfaces of SiO2 and A12O3, but also metals including alloys such as stainless steel with alkenes or alkynes under mild conditions by photochemical reaction. The process is very well suited to form patterned modified surfaces which are of use for example in microelectronics, biosensing and catalysis. La présente invention porte sur un procédé de modification ou de fonctionnalisation de surfaces d'oxyde, telles que des surfaces de SiO2 et Al2O3, mais également de métaux comprenant des alliages tels que de l'acier inoxydable avec des alcènes ou des alcynes dans des conditions douces par réaction photochimique. Le procédé est très bien approprié pour former des surfaces modifiées à motif qui sont d'utilité par exemple dans le domaine de la microélectronique, de la biodétection et de la catalyse.
