    The effects ofﾠcarbon nanotubeﾠ(CNT)ﾠsidewall fluorination on theﾠinterfaceﾠtoughness of theﾠCNTﾠepoxyﾠinterfaceﾠhave been comprehensively investigated. Nanoscale quantitative single-CNT pull-out experiments have been conducted on individual fluorinatedﾠCNTsﾠembedded in an epoxy matrix,ﾠin situ, within aﾠscanning electron microscopeﾠ(SEM)ﾠusing an InSEMﾮﾠnanoindenter assisted micro-device. Equations that were derived using a continuum fracture mechanics model have been applied to compute theﾠinterfacialﾠfracture energy values for the system. Theﾠinterfacialﾠfracture energy values have also been independently computed by modeling the fluorinated graphene-epoxyﾠinterfaceﾠusingﾠmolecular dynamics simulationsﾠandﾠadhesionﾠmechanisms have been proposed.
