With attempt to prolong the lifetime of the rubber products in dynamic sealing environment, a good tribological performance of fluoroether rubber is urgently needed. Herein, ionic liquid modified graphene (TrGO-IL) with fluffy and nano-porous morphologies was prepared via amidation reaction and thermal reduction. After that, TrGO-IL was mixed to neat fluoroether rubber to fabricate rubber composites (i.e. FM-TrGO-IL-1). The compatibility of rubber with TrGO-IL and the crosslinking density were simultaneously increased for FM-TrGO-IL-1 when compared the composite with unmodified graphene. More importantly, the friction coefficient and wear rate of FM-TrGO-IL-1 decreased by 13.1% and 59.8% respectively. Ionic liquid provided an effective self-lubricating layer on graphene, developing a good interface bonding of TrGO-IL with rubber matrix to enhance the friction and wear resistance of FM-TrGO-IL-1, as illustrated in morphology observations, vulcanization curves, mechanical and dynamic mechanical tests. Therefore, TrGO-IL may be very useful to serve fluoroether rubber products for their sealing applications.
