Title (EN) A METHOD TO SYNTHESIZE GRAPHENE-BASED AMPHIPHILIC JANUS NANOSHEETS
(FR) MÉTHODE DE SYNTHÈSE DE NANOFEUILLES DE TYPE JANUS AMPHIPHILES À BASE DE GRAPHÈNE
Abstract:
(EN) A facile and scalable method to prepare graphene-based amphiphilic Janus nanosheets with high efficiency utilizing the formation of hydrogen bonding to immobilize graphene oxide (GO) on the surfaces of starch microspheres. After selective functionalization of the exposed surface using alkylamine, amphiphilic Janus nanosheets (AJN) were obtained by releasing the nanosheets from the starch microspheres.
(FR) L'invention concerne une méthode facile et évolutive pour préparer des nanofeuilles de type Janus amphiphiles à base de graphène avec une efficacité élevée utilisant la formation d'une liaison hydrogène pour immobiliser l'oxyde de graphène (GO) sur les surfaces de microsphères d'amidon. Après fonctionnalisation sélective de la surface exposée à l'aide d'une alkylamine, des nanofeuilles de type Janus amphiphiles (AJN) ont été obtenues par libération des nanofeuilles des microsphères d'amidon.
