Title
(EN) SELF-CLEANING AND ANTI-FOULING GRAPHENE OXIDE/TIO2 PHOTOACTIVE COATING AND LARGE SCALE BONDING-TO- SURFACE PROCESS THEREOF
(FR) REVÊTEMENT PHOTOACTIF D'OXYDE DE GRAPHÈNE/TIO2 AUTONETTOYANT ET ANTISALISSURE, ET PROCÉDÉ À GRANDE ÉCHELLE DE COLLAGE DE CE DERNIER À UNE SURFACE
Abstract
(EN) Embodiments described herein related to photocatalytically active coatings having improved photocatalytic activity. Embodiments described herein also relate generally to methods for producing graphene-oxide/TiO2 materials and new applications based on the improved photoactivity of the materials. For example, the graphene-oxide/TiO2 can be used in enhanced self-cleaning coatings for surfaces including cement, metal, glass, and wood. Embodiments described herein also relate generally to methods of producing functionalized graphene oxide-TiO2 materials and methods of coatings by surface modification of a substrate and functionalization of the functionalized graphene oxide-TiO2, the functionalized composite being coated onto the target surface after proper surface treatment.
(FR) Des modes de réalisation décrits dans l'invention concernent des revêtements à activité photocatalytique présentant une activité photocatalytique améliorée. Les modes de réalisation décrits dans l'invention concernent aussi d'une manière générale des procédés de production de matériaux oxyde de graphène/TiO2, et de nouvelles applications se fondant sur la photoactivité améliorée des matériaux. Par exemple, l'oxyde de graphène/TiO2 peut être utilisé dans des revêtements autonettoyants améliorés pour des surfaces, parmi lesquelles le ciment, le métal, le verre et le bois. Les modes de réalisation décrits dans l'invention concernent aussi d'une manière générale des procédés de production de matériaux fonctionnalisés oxyde de graphène-TiO2 et des procédés de revêtement par modification en surface d'un substrat et fonctionnalisation de l'oxyde de graphène-TiO2 fonctionnalisé, le composite fonctionnalisé étant appliqué sur la surface cible après un traitement de surface approprié.
