Title (EN) LUBRICATION MATERIAL USING SELF-DISPERSED CRUMPLED GRAPHENE BALLS AS ADDITIVES IN OIL FOR FRICTION AND WEAR REDUCTION
(FR) MATÉRIAU DE LUBRIFICATION UTILISANT DES BILLES DE GRAPHÈNE FROISSÉES AUTO-DISPERSÉES EN TANT QU'ADDITIFS DANS L'HUILE POUR LA RÉDUCTION DES FROTTEMENTS ET DE L'USURE
Abstract:
(EN) A method for forming a lubrication material using self-dispersed crumpled graphene balls as additives in a lubricant base fluid for friction and wear reduction. The lubricant base fluid may be, for example, a polyalphaolefin type-4 (PAO4) oil. After the crumpled graphene balls are added as additives in the lubricant base fluid, the lubricant base fluid with the additives are sonicated for a sonicating time period, so that the crumpled graphene balls are self-dispersed in the lubricant base fluid to improve friction and wear properties of the lubricant base fluid. In some cases, a dispersing agent, such as Triethoxysilane, may be added in the lubricant base fluid to enhance stability of dispersion of the crumpled graphene balls in the lubricant base fluid. The crumpled graphene balls may stay stably dispersed in the lubricant base fluid between a lower temperature (such as -15 C) to a higher temperature (such as 90 C).
(FR) La présente invention concerne un procédé de formation d'un matériau de lubrification à l'aide de billes de graphène froissées auto-dispersées en tant qu'additifs dans un fluide à base de lubrifiant pour la réduction des frottements et de l'usure. Le fluide à base de lubrifiant peut être, par exemple, une huile poly-alpha-oléfine de type 4 (PAO4). Une fois les billes de graphène froissées ajoutées en tant qu'additifs dans le fluide à base de lubrifiant, le fluide à base de lubrifiant avec les additifs sont soumis à des ultrasons pendant une période de temps de sonication, de sorte que les billes de graphène froissées s'auto-dispersent dans le fluide à base de lubrifiant pour améliorer les propriétés anti-frottements et anti-usure du fluide à base de lubrifiant. Dans certains cas, un agent de dispersion, tel que le triéthoxysilane, peut être ajouté dans le fluide à base de lubrifiant pour améliorer la stabilité de la dispersion des billes de graphène froissées dans le fluide à base de lubrifiant. Les billes de graphène froissées peuvent rester dispersées de manière stable dans le fluide à base de lubrifiant entre une température inférieure (telle que -15 °C) et une température supérieure (telle que 90 °C).
